A staff member, who asked to remain anonymous, told the BBC that the trouble started after they informed customers that they had run out of new naira notes.

There have been long queues outside banks in recent weeks as Nigerians seek to exchange their old banknotes for new ones before the 10 February deadline - extended from 31 January.

Many banks have placed a limit because of the shortage to the frustration of customers.
