A teenager was caught in mid-air after he jumped over a fence to escape pursuing police and landed on a trampoline.

Police in the Western Australia city of Geraldton say the lucky catch came after the 17-year-old stole a scooter.

The scooter crashed as he tried to mount a kerb.

Police say the teenager then fled, jumped a fence and landed on the trampoline on the other side.

Sergeant Grant Rosman says the boy bounced back into the air, where police were able to catch him and pull him back over the fence.

"I think it was one of those situations where you probably couldn't repeat if you tried to," he said.

"It was just fortunate for the police - but not for him.

"Everyone was positioned correctly there and he bounced straight back into their arms."

The 17-year-old has been charged with seven offences, including drink driving and not wearing a helmet.
