Former East 17 star Brian Harvey was in a critical condition in hospital today after falling under the wheels of his own car.

The troubled singer underwent emergency surgery after being crushed beneath his Mercedes convertible in what his manager described as a "bizarre" accident as he drove to a recording session.

Harvey, who is alleged to have made two attempts on his own life, suffered multiple fractures to his legs and pelvis in the early hours of yesterday.

He is now undergoing treatment in the intensive care unit of Whipps Cross Hospital in east London.

Simon Harrison, the singer's manager, said the accident happened as Harvey drove through Chingford, Essex.

He said: "He was on his way to a studio session and from what we know he was reversing down a road in his own car with the door open, hit a number of parked vehicles and was actually thrown from his car.

"We presume at the moment he was actually crushed under his own car or against another car. It's all a little bizarre but that's what happened."

Mr Harrison confirmed the former chart star had suffered a "quite heavy depression" over the last six months, particularly since the death of his grandmother Betty.

She died as Harvey entered the ITV show I'm A Celebrity... Get Me Out Of Here!, an attempt to resurrect his career, prompting the singer quit the jungle on day two.

A week ago Harvey was taken to hospital after a reported overdose of sleeping tablets and alcohol - his second in a month.

The former boy band star has been diagnosed with clinical depression and split from girlfriend Emma B, who appeared on Five reality show The Farm, this month.

Harvey was temporarily thrown out of East 17 after he boasted of taking 12 ecstasy tablets in one night, and saw his career nosedive when he later left the band.

He was also attacked with a machete in a nightclub and declared himself bankrupt.
