Police have named a man they want to question about the kidnap at gunpoint of a man in south-east London.
People are warned not to approach Mr Callender
A 25-year-old man has been left with serious injuries after apparently being beaten and tortured for two days.
He was held after men surrounded his car, smashed their way in and bundled him into the back seat in New Cross, in the early hours of 1 September.
Police want to speak to Dwayne Callender, from Brockley, south-east London, about the alleged attack.
The victim was leaving work at 0130 BST that Thursday when he was allegedly kidnapped in his own car in Musgrove Road and threatened with a gun.
Long-term medical treatment
Blindfolded and gagged he was held at an unknown address - thought to be near a main road with metal bars or red grills on the window - until the early hours of 3 September.
While there he has claimed he was threatened, beaten and tortured. A police spokesman said: "He received very serious injuries and will require long-term medical treatment to make a full recovery."
He was then moved to another address, where he was found by someone visiting the property.
Mr Callender is described as black, 5ft 9", of an athletic build with a distinctive gold tooth.
Although he is from Brockley, he is known to visit Camberwell, south London, and St Mary Cray, Bromley, regularly.
Police say he should not be approached and people should contact them if they see him.
