Friends and family of a woman arrested in Greater Manchester as part of an ongoing anti-terrorism investigation have staged a protest over her arrest.
The 26-year-old was detained under the Terrorism Act after police officers raided a house in Radcliffe, Bury, on Tuesday afternoon.
Protestors gathered to say prayers outside Pendleton police station in Salford where the woman is being held.
She is the fourth person arrested by GMP's Anti-Terrorist Unit in a month.
Police say they are investigating terrorist financing, travel patterns and those going to terror camps abroad.
A man arrested on 23 August as part of the same investigation remains in custody while two men arrested on 2 September were released on Friday.
Officers are also looking at suspected links to banned radical Islamic group Al-Muhajiroun.
Deputy Chief Constable Dave Whatton, of Greater Manchester Police, said: "This is an international investigation which began many months ago and has involved co-operation between several law enforcement agencies.
"It is a very complex investigation and a team of officers are involved in reviewing around a thousand items that have been recovered.
"A significant amount of material has also been recovered from computers, and it is equivalent to nine articulated lorries full of paper."
Translators have been drafted in to help assess the content of the material found.
This latest arrest is not linked to the alleged terror plot to blow up transatlantic airliners or the July 7 bombings of 2005.
