A man is fighting for life in hospital after being struck down by a hit-and-run driver near the Olympic Park.
The pedestrian, aged in his 30s, was hit by a car in High Street, Stratford, at around 4.40pm on Bank Holiday Monday.
Police officers on routine patrol witnessed the crash and saw the car drive off immediately after without stopping.
The victim was rushed to an east London hospital by ambulance where he remained in a “critical” condition on Sunday evening. An Air Ambulance was also scrambled to the scene.
Police said that the same car was involved in another crash with two vehicles a minute later in Westfield Avenue, where it was abandoned.
There were reports of minor injuries from the second collision but nobody is believed to have required hospital treatment.
Three males were arrested nearby soon after and have now been taken into custody at an east London police station.
Detectives from Newham are investigating alongside officers from the Roads and Transport Policing Command.
High Street, which is minutes from the site of the 2012 Olympics, was closed for three hours on Monday evening while emergency services carried out work.
Anyone who witnessed the collisions, or who has information that may assist the investigation, is urged to call police via 101.
