Four men have been arrested after the carjack killing of Harjinder Singh Bhurji in east London.
Three males, aged 20, 19, and 17 are being held on suspicion of murder, according to Scotland Yard.
A fourth man is being held on suspicion of handling stolen goods.
Bhurji, 32, was stabbed in the chest after he refused to give carjackers the keys to his black Mercedes CLK coupe.
The victim, who lived in Ilford, east London, was sitting in the car with a female friend, when a man dragged her from the car.
Bhurji tried to hide the keys, but the man threatened to harm his friend if he didn’t hand them over.
He went to retrieve the keys but was stabbed before thieves drove off with his car.
Bhurji was pronounced dead at the scene with his friend, who was uninjured but in shock.
The car was found abandoned at 2.45am in Forest Glade, Chingford.
The victim’s best friend Gurmit Birdi, 32, said Bhurji’s family was “distraught”.
He added: "He was a very nice person – he never did anything wrong.
“He lived his life and enjoyed his life … he was a happy person. He was just in the wrong place at the wrong time.
"For his family and friends, this is just unbelievable. I can't even think straight – God knows what his family are going through."
