A murder investigation has been launched after a teenage boy was stabbed to death and another hospitalised.

Police found a 16-year-old suffering from stab wounds after being called to reports of a fight outside a fast food restaurant in Church Elm Lane, Dagenham at 6.20pm on Saturday.

The teenager was given first aid before being rushed by ambulance to an east London hospital. He is said to be in a stable condition.

Minutes later officers were alerted to nearby Wyhill Walk by paramedics where they found a 17-year-old boy with stab injuries.

Despite efforts to save him, the boy was pronounced dead in hospital on Sunday morning at 3.25am.

Photos from the scene showed police tape cordoning off the area around Church Elm Lane.

Next of kin have been informed, formal identification is yet to take place. A post-mortem examination will be held in due course.

Detectives are investigating to see whether both victims were hurt in the same incident.

No arrests have been made and enquiries continue.
