Two men have been arrested after a Christmas fairground ride "failed and crashed" in Birmingham city centre.
Two women were taken to hospital after the City Star Flyer ride in Centenary Square failed on Thursday evening, while around a dozen other patients were assessed and discharged at the scene.
The men, aged 55 and 21, were arrested at the scene on the same evening on suspicion of perverting the course of justice and obstructing officers.

A police cordon remained in place around the ride, which is 55m high, on Friday morning.
West Midlands Fire Service said the ride "dropped to ground level whilst in operation".
According to West Midlands Ambulance Service, the women's injuries are "not believed to be serious".
"On arrival, crews found 13 patients," the ambulance service said.
"Two women were treated by ambulance staff for injuries not believed to be serious and conveyed to Midland Metropolitan University Hospital.
