Detectives have arrested a man at Heathrow on suspicion of murder, hours after a man was hit by a car and killed in east London. The Metropolitan police launched an investigation after being called at 5.11am to reports of a collision involving a car and pedestrian in East Ham. A 35-year-old man was found injured at the scene on Barking Road, near to the junction with Arragon Road. Officers responded and provided first aid, but despite the efforts of the emergency services, the man died a short time later. Urgent inquiries led to the arrest of a 33-year-old man at Heathrow at about 3.30pm on Sunday. He has been detained on suspicion of murder, and a 30-year-old woman has been arrested on suspicion of assisting an offender. Both remain in custody. DCI Joanna Yorke, leading the investigation, said: “My thoughts are with the victim’s family at what will be an incredibly difficult time for them. Our family liaison officers will support them as our inquiries continue. “I am aware that a large number of people had been at an event in Barking Road overnight and many would have witnessed the incident. I am appealing for those people to come forward immediately. Your information could be vital to the investigation.” Yorke said that while “we do not believe there to be any risk to the wider community”, officers will be posted in the area over the coming days to give residents peace of mind. Anyone with information is asked to call police on 101, quoting reference CAD 1281/24Mar.
