A suspect has been detained at Heathrow Airport in connection with the Manchester Arena bombing.

Greater Manchester Police said that the arrest had been pre-planned and that the airport was not in any danger.

The 38-year-old has now been hauled under custody, where he remains under the Terrorism Act.

He becomes the 19th person to be arrested in connection with the attack, which killed 22 people, but 12 have already been released without charge.

'The 38-year-old was arrested on suspicion of offences contrary to the Terrorism Act and remains in custody,' Greater Manchester Police said in a statement on Twitter.

'The arrest was planned beforehand and there was no direct threat to the airport.'

Yesterday, it emerged that bomber Salman Abedi may have used a Nissan Micra to store items used to assemble his deadly device.

Abedi murdered 22 people, including seven children, after detonating an improvised explosive device after a concert by US singer Ariana Grande on May 22.

Abedi made 'repeated trips' to and from the car between 18 and 22 May, and police have since found 'significant evidence' in the vehicle.

Officers are now hunting for possible accomplices who may have used the car and helped plan the terror attack.

Greater Manchester Police issued photos of the Nissan and a red and black holdall and appealed for anyone who recognised either to come forward.

Police said 'significant evidence' was found in the white car, which has an 'R' registration plate and was seized from Devell House in Rusholme on Friday.

Just days ago shops, homes and student halls were evacuated as anti-terror police swooped on the car.

Officers threw a 100-metre cordon around the white Nissan Micra parked in the south of the city amid fears the vehicle could be booby-trapped, before it was towed away.

Detective Chief Superintendent Russ Jackson said police were continuing to track the movements Abedi made in the days leading up to the attack.

Mr Jackson said it was 'vital' officers exhausted all lines of enquiry to establish how other people were involved in planning the attack.

He said: 'Our investigation has also revealed that Abedi made repeated trips to and from this car between 18 and 22 May 2017 and we believe he was taking items from the car to help assemble the device.

'The car was sold by a previous keeper on 13 April 2017.

'Abedi left the country on 15 April and it is vital that we understand what happened to this car during these few days between 13 and 15 April.

'We need to know who was in the car and where the car went. You may have seen the car and not realised at the time but it could have stopped at a newsagents or a supermarket - did you see the car and its occupants during these dates?'

He added: 'We also appeal to anyone who knew Abedi or his close associates to come forward. Did you notice anything suspicious about him or people he associated with? This information could be vital in piecing together what happened.'
