A cyclist is in a critical condition after being kicked off his bike into a parked car by another rider in an incident captured on CCTV.
The 30-year-old victim was riding his bike in Wallis Road, Hackney, east London, on Sunday at around 12.45pm when another cyclist caught him up and began to cycle alongside him.
Scotland Yard said his attacker then kicked the victim off his bike before riding away in the direction of Berkshire Road.
The victim was taken by ambulance to an east London hospital, where his condition is critical.
The motive for the attack is not known, according to police, who have released footage of the incident.
The suspect is described as a white male in his 20s or 30s and police also want to hear from anyone who may have been threatened or assaulted by him in and around Hackney.
