London: A 16-year-old boy has been arrested by Scotland Yard in connection with the killing of an Indian-origin man who was found stabbed near a tennis court in west London, taking the total number of suspects nabbed in the case to five.

Harjit Singh Dulai was found bleeding by Rosdale Park tennis court in Hayes area of the city by paramedics last Wednesday and rushed to hospital where he died soon after. A post-mortem on Friday found that a stab wound had caused the 44-year-old's death and a murder investigation was launched.

The teenager arrested yesterday is the latest suspect in the murder. Four other men have also been arrested as part of the investigation on suspicion of murder. All suspects have been bailed pending further enquiries and will appear in court later this month. One of the men was arrested at the scene while the other three were arrested shortly after.

A sixth man, aged 39, who was also arrested on suspicion of murder, has been released with no further action. "Our investigation into Harjit's murder continues at pace and I would reiterate my appeal to anyone with information to contact my officers," said Detective Chief Inspector Noel McHugh, of the Metropolitan Police Homicide and Major Crime Command.

"There are people who will know exactly what happened to Harjit and I would urge those who have information to come forward. Any information provided will be dealt with discretely and sensitively," he said.
