MAN HELD IN TERROR PROBE

The man, who is believed to be white, is the fourth person from Blackburn to be arrested for terror offences in the last two weeks.

Lancashire Police arrested the man at 6.40am. Specialist officers were searching an address in the Whalley Range area of the town.

The man was arrested on suspicion of committing offences under the Terrorism Act 2006.

A police spokeswoman said: "The arrest is part of an ongoing investigation by Lancashire Constabulary and Greater Manchester Counter Terrorism Unit."

Three men, aged 21, 22 and 23, are being questioned by police after two were arrested at Manchester Airport and one in Accrington on August 14.

The three men are linked to an investigation into threats to kill the Prime Minister, according to police sources.

No plot was in place but there were calls for the death of Gordon Brown on an extremist jihad website in January.

The internet hosts many websites from groups and individuals claiming allegiance to al Qaida and Osama bin Laden who routinely issue warnings and threats to political leaders in the UK and the US over the West's involvement in the Middle East.

The three suspects are being held under the Terrorism Act 2006.
