Apensioner has been arrested after a suspected burglar was killed during a violent tussle at his home.
The 78-year-old was held on suspicion of murder after the 38-year-old died of his wounds in hospital in the early hours of Wednesday morning.
Police said the struggle broke out after the pensioner had found two men inside his home in South Park, Hither Green, south London shortly after midnight.
One suspect, armed with a screwdriver, forced the home-owner into his kitchen when he discovered them, while his accomplice went upstairs.
Detectives believe a struggle ensued between "one of the males and the home-owner" and the 38-year-old intruder was stabbed in the upper body.
