Detective Superintendent Lewis Basford, responsible for policing in Barking and Dagenham, said: “This is a truly shocking attack and I want to thank local residents for their assistance and patience while we deal with this incident.
“At this early stage, we believe those involved were known to each other and we are not looking for anyone else in connection with this incident.
“A crime scene will remain in place for some time while our officers carry out vital work and you will see an increased policing presence in the area over the coming days.”
The London Ambulance Service and London’s Air Ambulance were also sent to the scene.
