London police said they had charged another man under anti-terror laws in relation to the failed London bombings on July 21.
Abdul Sharif, 28, of south London was on Wednesday charged with withholding information that could have helped police apprehend bombing suspect Osman Hussain, also known as Hamdi Issac.
Sharif, who has been in police custody since his arrest on August 1, will appear at London's Bow Street Magistrates Court on Thursday.

Police allege that Sharif failed to disclose information that he knew, or believed, may have helped police secure the arrest, prosecution or conviction of a person involved in the 'commission, preparation or instigation of an act of terrorism,' metropolitan police said in a statement.
Hussain fled Britain after the failed bomb attacks and is being held in Italy on international terrorism charges. Britain wants to extradite him back to the UK to face charges.
