A FOURTH Blackburn man has been charged with involvement in terrorism.

Muhammad Ali Mumtaz Ahmad, 24, a white man of Whalley Range, is due to appear before Westminster Magistrates’ Court tomorrow.

He was arrested six days ago at his home by police investigating an alleged threat to kill Prime Minister Gordon Brown and his predecessor Tony Blair.

Tonight Ahmad was charged with possessing terrorist material after being held in custody for six days.

On Friday three Blackburn men arrested on August 14 as part of the same investigation appeared before the London court charged with terrorism offences.

Ishaq Kanmi, 22, of Cromwell Street, Audley Range, is accused of threatening to "eliminate" Mr Brown and Mr Blair, being a member of al Qaeda, and encouraging others to join the organisation.

He is accused of spreading terrorist literature along with co-defendant Abbas Iqbal, 23 of Percival Street, Whalley Range.

Aqbal is also charged with owning terrorist material, including camouflage equipment.

Iqbal's brother Ilyas, 21, also of Percival Street, was accused of possessing terrorist material and conducting research into terror.

He pleaded not guilty to all charges. All were remanded in custody.

A fifth man, arrested in Derby last Tuesday, remains in custody.
