Bumbling robber charged after WA hold-up

A suspect in a Perth pharmacy hold-up allegedly dropped cash and tried to hide in the back of a parked car with the driver still in it.

The 33-year-old is accused of robbing a Gosnells pharmacy on Sunday afternoon, then dropping half of the cash on the road as he ran off.

With the sound of approaching police sirens blaring, he allegedly climbed into the back of a car parked nearby - surprising the driver, who leapt out and alerted police.

The man has been charged with armed robbery and is due to appear in the Armadale Magistrates Court on Monday.
