Robbers have been kidnapping students in Manchester city centre in an Audi A6 before forcing them to withdraw cash and transfer thousands of pounds online.

Police have received four reports of innocent members of the public, some of them students new to the city, being lured into a high-end motor this week.

Some were forced to make online transfers of £3,000 from their bank accounts before being let out of the car, police said.

Others were driven to petrol stations, forced to withdraw cash, fill the car up with petrol, then get more cash out after midnight.

On Friday, police foiled another robbery, discovering a 19-year-old kidnap victim inside a car matching the description of the dark Audi A6.

All the men are in police custody for questioning.

All four victims were kidnapped in the city centre between Wednesday, September 19 and Friday, September 21.

Detective Constable Natalie McDonald of GMP’s City of Manchester team said : “Innocent members of the public, some of them students new to Manchester, have been victims of tricksters who then kidnapped them and forced them to hand over their money.

“Last night, thanks to some excellent work by the TVIU, four people were arrested, during what we believe was another robbery.

“When a person is a victim of such robbery, they can be left feeling scared to go out and can lose trust in everyone.

“This week we have many new students coming to live in Manchester, and it is disappointing that some of their first memories of our city is that they were victims of crime.

“I would like to reassure everyone that we are doing all that we can to prevent criminals from taking advantage, we have strong links with the universities and the councils and we have officers on dedicated patrols as part of the Student Safe campaign.”
