Three people arrested on suspicion of terror offences linked to Syria have been released without charge, Greater Manchester Police said.
They were arrested on Tuesday by counter-terrorism officers on suspicion of being involved in travelling to or supporting fighting in war zones.
Two men aged 24 and 18, both from Levenshulme, and a 21-year-old woman from Trafford were held in Manchester.
A fourth person, 29-year-old Jamshed Javeed, was charged with the intention of assisting others to commit acts of terrorism and engaging in conduct in preparation for giving effect to his intention.
Javeed appeared at London's Westminster Magistrates' Court yesterday and a preliminary date of April 4 was set for his next appearance at the Old Bailey.
