A THIRD man has been arrested after a teenager was murdered at a block of flats in Deptford.

Adam Pervaiz was found in a communal stairwell in Shearwater Court, Abinger Grove, at around noon on Thursday (May 7).

The 18-year-old had been stabbed and was pronounced dead at the scene.

A post-mortem examination held on Friday at Greenwich mortuary gave the cause of death as stab wounds to the leg.

Police arrested a 20-year-old man yesterday in connection with the death and he has been taken to a south London police station for questioning.

Two other men, aged 20 and 18, were arrested on suspicion of murder shortly after the killing.

The 20-year-old has been bailed until a date in June and the 18-year-old has been released without charge.
