The significance of the banking sector in any country stems from its role of financial mobilization  from  surplus  to  deficit  unitp, rovision  of  a  competent  payment  system  and facilitation  of  the  implementation  of  monetary  policies.  In  intermediatiboann, ks  mobilize savings from the surplus units of the economy and channel these funds to the deficit unit, particularly private business enterprises, for the purposes of expanding their productive capacity.
The banking sector has become one ofmthoest crtiical sectors in the economy with wide effect on the level and direction of economic growth and transformation and on such economic variables as the rate of unemployment and inflation which directly athffeclitves of our people.

camouflage, or exclusion of the truth for the purpose of dishonesty/stage management to the financial damage of an individual or an orgzaantion. Going by the definition of the chambers universal learners dictionary Kirkpatrick (1985) define fraud as any person who pretends to be something that he is not is a fraud, a snare, a deceptive, trick, cheat and a swindler.
ÂÂ
Having explained what fraud is, it is pertinent to define bank fraud which is the subject matter of this study; however bank fraud is the use of fraudulent means to obtain money, asostehtesr, or
property owned  or  held  by  a  financial  institution,  or  to  aoibnt money  from  depositors  by
ÂÂ
fraudulently representing to be a bank or financial institution. For an action to constitute fraud there must be a dishonest intention and the action must be intended to benefit the perpetrators to the detriment of another peorns.
Going by the definitions, frauds in Nigeria cannot be restricted to the banks alone. A lot of fraudulent activities are prevalent in Nigerian economy ranging from bloody killings, ritual, kidnapping, robberies, forgery, misappropriation, cheating, gaanndgsters and looting. Bank fraud  ranges from accou-notpening, money transfer fraud, cheque kiting, telex fraud, money laundering fraud, computer fraud, loans fraud and the likes.
According to Oseni (2006) the incessant frauds in the banking industryetatirneggto a level at
ÂÂ
which many stakeholders in the industry are losing their trust and confidence in the industry. Corroborating the view of Oseni, Idorlo(2010), stressed that the spate of fraud in Nigerian banking sector has lately become a source obfaerrmassment to the nation as apparent in the seeming attempts of the law enforcement agencies to successfully track down culprits. Although the incidence of frauds is neither limited to the banking industry nor peculiar to Nigeria economy, however the higrhate of fraud within the banking indus,trcyalls for urgent attention
with a view to finding solutions.
ÂÂ
Fraud in its effect reduces organizational assets and increases its liabilities. With regards to banking industry,it may engender crises of confidenacme ong the banking public, impede the going concern status of the bank and ultimately lead to bank fa(Ailudreeyemo,2012).
ÂÂ
According to kimani (2011) `A way of making money is to stop losing it. The level of fraud in the present day Nigeria has assumedepaindemic dimension. It has eaten deep into every aspect of our life to the extent that a three years old child talks aboutth4e19n,ame give to the newly discovered advanced fee fraud that is hunting our nation.
In  July  2004,  central  bank  of  Nigeria  (CB) Nunveiled  new  banking  guidelines  designed  to consolidate  and  restructure  the  industry  throumgehrgers  and  acquisition.  Basnkand  Other Financial Institutions Ac(tBOFIA) 1991, section 15, waaslso designed to prevent fraud and to make Nigeria banks more competitive and able to play in the global market.
The Nigeria Deposit Insurance Corporation (NDIC) 2007 annual report and statement of accounts report that cases of attempted frauds and ifeosrgienr insured banks, as at 2007 exceeded what was recorded in the year 2006. For instance, the NDIC report for 2007 disclosed that a total of 1,553 reported cases of attempted sfranud forgeries involving over symbols•10
billion compare with 1,193 reprtoed cases offraud and forgeries involving •4,832.17 billion  in
ÂÂ
the year 2006. The foregoing statistics clearly unfolds the extent to which fraud had had eaten deep into the financial strength benefit the perpetrators to the department of another person.
Today, banks cannot withstand the growing pressure of competition among various banks due to the monster called bank frauds. If this act of fraud is not taerdr,esit might delete our resources because foreign investors might not find it wise to transascint ebsus via our banks.
ÂÂ
Banks generally have been experiencing fraud since its evolution. This affects the performance
ÂÂ
and the profitabiltiy of banks and may possibly ldeato distres.s The inability to identify the
ÂÂ
immediateand remote causes of continuous cases of bank frauds in virtually all banks in Nigeria is one of the problems brought to b.are
Fraud is a major challenge to the entire banking industry; no bank is immuitnaentdo in all facets of life (Olorunsegun,  201)0. The banking public expects accountability, fairness, transparency in their day operation for effective intermediation.
Though there were known cases of fraud in the sector, one major question still remain
ÂÂ
unanswered  which  is  what  is  the  nature  and  rdeinffte ways  through  which  fraud  can  be
ÂÂ
perpetuated in banks. It is asserted by Adeyemo (2012) that fraud in the bank is possible with corroboration of an insider. The banks aerxepected to ensure that they carry out their responsibilities with sincerity ofuprpose which is devoid of fraudulent practices. This is relevant
if the banking sector is to gain public trust and goodwill.
ÂÂ
Another problem is that the government and its agencies have not put enough effort in the prevention and control of bank fraud Ninigeria; otherwise the level of bank fraud would have reduced  to  a  bearable  level.  Agencies  limkeoney  laundering  Actwhich  helps  to  place surveillance on any account through which such excess cash deposits or withdrawals are made, Nigeria Deposit InsurancCeorporation which is involved in managing bank distress, failed banks and financial malpractices in banks Awcthich was vested with powers to recover the debts of failed banks, dishonored cqhuees Act which affects banks in their collection and payment of cheques on behalf of their customers and Bill of Exchange Act which helps to collect the proceeds of trade bills of exchange and cheques are not putting enough effort in the prevention
and control of bank fraud that is the reason why bank fraud is inncgredaasyi  by day in Nigeria.
ÂÂ
However, environmental or social factors pose a problem in the activities of banking industry as they contribute to bank fraud in Nigeria. Environmental factors are those that can be trace to the
ÂÂ
immediate and remote environmeonft the bank these factors are manifest in the following manne;r the desire to get rich quick slow and complex legal process, poverty and the widening gap between the rich and the pocoor,mpetition among bank staff, the desire to belong to any social classj,ob insecurity, peer group pressure and societal expectations.
