Abu Hamza's son is the suspect held in connection with the murder of a doorman outside an exclusive Mayfair party on New Year's Eve, MailOnline can exclusively reveal today.

Imran Mostafa Kamel, 26, whose radical preacher father was extradited to the US in 2012, was arrested after Tudor Simionov was knifed in the chest when violence erupted on Park Lane at about 5.30am on Wednesday.

Mr Simionov fought off up to nine men seconds before being stabbed to death outside 80 Park Lane - where a private £2,000-a-table gathering allegedly organised by Lord Edward Davenport was going on.

Today Scotland Yard said Kamel has been charged with possession of a firearm with intent to cause fear or danger, and possession of a firearm when prohibited for life.

Kamel appeared at Westminster Magistrates Court this afternoon - but remains a suspect in the murder on January 1 after being released under investigation.

MailOnline can reveal Kamel's father is Abu Hamza, 60, the former imam of the Finsbury Park mosque whose radical views brought him to the attention of the authorities.
