Police investigating the murder of a 32-year-old man in Clapham have made a third arrest.
He was pronounced dead at the scene; a post mortem examination gave the cause of death as "compression to the neck".
Police said that such an injury was "consistent with the victim being held in a headlock for a prolonged period."
On Monday a 29-year-old was arrested on suspicion of murder and burglary. He has been released under investigation.
