Detectives have arrested a boy after a teenage cyclist appeared to be deliberately dragged under a car.

The 16-year-old was arrested on suspicion of attempted murder on Tuesday, September 10 and taken to an east London police station for questioning.

Officers were called to the junction between Poplar High Street and Bazely Street, Poplar, at 6.59pm on Monday, September 9.

Police and paramedics found a maroon Ford Focus following a suspected collision with the 17-year old cyclist.

A Met spokeswoman said: "The cyclist was taken to hospital, initially in a critical condition. His injuries have now been assessed as life-changing."

The driver of the car fled the scene, police said.

Det Sgt Lauren Brady said in an appeal made earlier: "This is being treated as a grievous bodily harm with intent investigation.

"We believe the victim was deliberately targeted and was dragged a significant distance underneath the vehicle."

She urged witnesses and anyone who hasn't contacted police, or people with any dash-cam footage, to call police via 101 quoting reference Cad 6546/09Sep.
