The tailor

A tailor needed some cash to start a business.  He went to the bank and applied for a loan.  After a week, he went to the ATM to withdraw some 5,000 shillings to buy materials.  To his dismay, the balance in his account was only 300 shillings.  Who had withdrawn his money?  Had anybody stolen his card or got access to his PIN number?  The bank promised to investigate the matter, but the tailor was very persimistic as bank frauds were very common those days.
