Police are investigating an apparent "booby trap" that injured a 16-year-old girl when she tripped over barbed wire strung across the road in the eastern Perth suburb of High Wycombe.

Sixteen year old Maddison White was jogging along Upton Road on Monday night when she was caught in what appeared to be a trap.

Police say one end of the wire had been tied to a power pole, with the other end rolled up and placed on the verge.

The teenager received minor injuries.

Her mother Michelle White told ABC local radio her daughter was shaken by the incident.

"She'd tripped over and hurt her leg on some barbed wire that had been strung across the road, across the footpath and attached to a light post," Mrs White said.

"It hit her mid-shin, caused little bit of a scratch and she tripped over.

"She was shocked that it was barbed wire and that it was deliberate."

Mrs White said it could have been worse if a child or an elderly person had been caught by the wire.

"It's situated near the skate park and it gets a lot of traffic with skateboards and scooters and bike with lots of kid action around that area," she said.

Anyone with information is urged to contact police.
