Mosque warned police about bomb suspect 2 years ago

Leaders at a South London mosque wrote to police complaining Hussein Osman, the alleged Shepherd's Bush attempted bomber currently fighting extradition from Italy, and associates were harassing more moderate Muslims to convert them to more radical views. But they said police did little to get rid of the gang who were "brainwashing" and "intimidating" members of the mosque.

It is thought Osman and his gang targeted Stockwell Mosque after police closed down the notorious base for radical Muslims, Finsbury Mosque in North London.

The gang sprayed verses of the Koran on the mosque and allegedly attacked members of the congregation, in an attempt to take over.

The Metropolitan Police last night refused to comment on "confidential" correspondence. The warnings about Osman emerged as it was confirmed a Scotland Yard detective is to fly to Rome to question the terror suspect.

The judge handling Osman's extradition hearing is also expected to attend the interrogation on Tuesday. It will be the first time Osman - also known as Hamdi Isaac - has been questioned by British authorities since he was captured in a Rome flat last week.

Meanwhile, the Bank of England yesterday revealed personal bank details held by the 21 July suspects showing they used multiple aliases and addresses to open dozens of bank accounts.

Some are also alleged to have claimed several nationalities, ages, and national insurance numbers. The information was revealed as the bank announced it was freezing accounts held by the four suspects, Osman, Ramzi Mohammed, Yassin Omar, and Mohammed Said.

A statement on the Bank of England website said: "The Bank of England, as agent for Her Majesty's Treasury, has today directed that any funds held for or on behalf of the individuals named must be frozen, and that no funds should be made available, except under the authority of a licence."
