Four arrested at Manchester Airport on suspicion of terrorism
Four people have been arrested at Manchester Airport on suspicion of terrorism, police have said.
Two others were arrested on Tuesday as part of the same investigation, launched after nine people were stopped on the Turkey-Syria border on 1 April.
The four are aged between 22 and 47 and are all from Rochdale, Greater Manchester Police said.
Two men aged 21 and 31 had been arrested on Tuesday, on suspicion of terrorism.
One was arrested at Birmingham Airport after being deported from Turkey. The other was arrested in the Rochdale area.
'No imminent threat'
The six arrested people remain in custody.
The group of nine detained in Turkey included five adults and four children.
Greater Manchester Police said officers were working to establish their reason for travel and apparent attempted entry into Syria.
Officers searched houses in the Rochdale borough as part of the investigation and police said no evidence was found to suggest any "imminent threat" to Rochdale or the rest of the UK.
Greater Manchester Police said in a statement: "Officers continue to work closely with Rochdale Borough Council, local partners, and faith leaders as part of the 'Prevent' initiative."
Footage released on Sunday shows Mr Ahmed leaving a police station in Hatay in Turkey, before getting a coach to Antalya.
His father, Rochdale Labour councillor Shakil Ahmed, said he had thought his son was on holiday.
In a statement he said: "My son is a good Muslim and his loyalties belong to Britain, so I don't understand what he's doing there."
