A man has been arrested after a suspected hit-and-run collision between a cyclist and a pedestrian left a middle-aged woman fighting for her life.

The 56-year-old victim was struck by an electric “mountain style” bike as she attempted to cross Kingsland High Street in Dalston, East London, just after 5pm on Tuesday.

Scotland Yard said the male cyclist initially stopped after falling off his bike, but then quickly fled the scene and ditched his dark red motorised “e-bike” a mile away.

He is believed to have run a red light.

Scotland Yard said the suspect had been arrested at an address in Islington, north London, after he contacted police late on Wednesday.

The 30-year-old was held on suspicion of causing bodily harm under Section 35 of the Offence Against Person Act, which covers incidents “injuring persons by furious driving”.
