A 78-year-old man has been arrested on suspicion of murder after a suspected burglar was stabbed to death.
The homeowner discovered two intruders in Further Green Road, Hither Green, south-east London, at about 00:45 BST.
One suspect, armed with a screwdriver, forced the man into his kitchen where a struggle ensued and he was stabbed, Scotland Yard said.
The 38-year-old was taken to hospital by paramedics but was pronounced dead at 03:40.
The pensioner, who suffered bruising to his arms, has been arrested on suspicion of murder.
He remains in custody at a south London police station.
Police said they were called to the property over reports of a burglary where they found a man with a stab wound to the upper body.
The dead man’s next of kin have been informed and a post-mortem examination would take place “in due course”, the Met added.
The second suspect remains at large.
