Bus driver arrested after double-decker smashes into bridge
Three people remain in hospital with serious injuries
The driver of a double-decker bus which collided with a bridge in Salford, seriously injuring three people, has been arrested.
Police have confirmed three people, a woman and two men, are still being treated for serious injuries in hospital.
The crash tore the roof off the bus on Monday afternoon, and one passenger was "ejected" from the top deck, according to Greater Manchester Police.
17 other casualties were treated at the scene for injuries, the force said.
Police said the bus driver, a man in his 50s, was arrested on suspicion of causing serious injury by careless driving and has since been bailed pending further investigations.
Emergency services were called at about 3pm on Monday to reports the bus had collided with the Bridgewater Canal Aqueduct on Barton Lane in Eccles.
A major incident was declared by North West Ambulance Service and 10 emergency ambulances, advanced paramedics and the Hazard Area Response Team, along with North West Air Ambulance, were dispatched.
Police believe the bus had come off its expected route and height restriction warnings, including hanging chains and signage, had not been complied with before the crash.
The force's Serious Collision Investigation Unit has appealed for anyone who witnessed the incident or has footage, including from a dashcam, mobile phone or doorbell, to come forward.
