An armed man's attempt to rob a Melbourne pub while wearing underwear on his head and a cape has hit the skids.
Wearing a makeshift disguise, the would-be robber demanded cash and threatened a staff member with a firearm at a Port Melbourne hotel early on Wednesday.
His plan fell flat when staff couldn't access any money, and the agitated man fled empty-handed.
No one was injured and police patrols failed to find the man.
Police released CCTV footage on Monday in a bid to identify the bumbling culprit.
The footage shows the man wearing dark material draped around him like a cape and dark-coloured underpants on his head.
He tripped on the 'cape' and fell while fleeing the scene.
Anyone with information is urged to contact Crime Stoppers.
