A 50-year-old man found stabbed to death in a house is believed to be the 11th murder victim in the capital in just 13 days.

Metropolitan Police officers forced their way into the property in Tooting, south London after they received a call from a concerned member of the public.

The victim, who had been stabbed, was pronounced dead at the scene, detectives said.

The force launched a murder investigation following the discovery of the body at the house in Tooting High Street at 3.12pm on Monday.

A post mortem examination is due to take place later today. So far no arrests have been made.

His death comes a day after the tenth person to be murdered in London in just 12 days was named as the son of a Nigerian politician who was given an award for saving a woman from a sex attack.

Abraham Badru, 26, was shot dead near his family's home in Hackney on Sunday night at around 11pm.

Paying tribute to his son, father Dolapo Badru, 62, a member of the Nigerian Assembly, similar to the House of Commons in the UK, described him as 'quiet and hard-working'.

He told the Evening Standard: 'A few years ago a girl was raped on the estate and Abraham fought them off. He went to court to testify against them and the police gave him an award.'

Mr Badru died with his mother at his side, with witnesses saying she 'collapsed in tears' on the pavement.

Concerns have been raised about rising levels of violent crime in the UK, and earlier this month eight people were shot or stabbed in London in the space of a week.

Patrick Green, chief executive of knife-crime awareness charity the Ben Kinsella Trust, said a 'crisis point' had been reached.
