A taxi driver decapitated himself in his cab in what appears to have been a gruesome suicide.

The man, believed to be in his 30s, tied a rope to a lamppost and the other end around his neck before driving off in Southwark, southeast London, on Friday.

His body was found by police slumped in the car — with his severed head yards away.

Police are treating the driver's death as suicide and are trying to trace his next of kin.

Officers were called at 12.40 a.m. Friday to the horrific scene in Great Suffolk Street, where the car had crashed into a pillar.

"Officers attended and the driver was found dead inside the vehicle," a spokesman for the Metropolitan Police said.
