One of the terror suspects was thrown out of a local mosque two years ago after shouting that voting in a General Election was 'un-Islamic', MailOnline can disclose.

The man had been attending the Jabir Bin Zayd mosque in Barking for some months when he aggressively interrupted a sermon in which the Imam was advising his community to vote.

'He started saying that voting was un-Islamic and we shouldn't do it,' the mosque manager, who declined to be named, told MailOnline.

'He got very angry. I called him aside and said, please calm down. He refused, so I removed him. Thank God he followed me.

'When we got outside the room, he said you don't have authority over me, only God has authority because this is a house of God. I said that might be true, but I am in charge.'

The suspect had long hair at the time, the manager said, and did not appear to know much about Islam.

'He had no special friends here. He would arrive, pray and then leave. He said hello to people but generally kept himself to himself,' the manager said.

'He seemed an uneducated person. He seemed to have no knowledge of religion.' After the outburst the suspect was banned from the mosque and has not been seen there since, he added.
