A wild police chase has unfolded near a Perth train station, with a 4WD towing a trailer without wheels under a lowering boom gate to escape the unmarked police cars trailing in pursuit.

Remarkable footage shows the Landcrusier narrowly missing the gate on Kelvin Road as sparks fly from the back of the trailer that is being dragged across the pavement.

A WA Police spokesperson told Yahoo7 News that the 4WD stopped failed to stop on Phillip Road in Maddington just before 7.40pm on Tuesday night.

They said the wheels became dislodged from the trailer, however the motorist failed to pull over when flagged down by police.
