An armed man's attempt to rob a Melbourne pub while wearing underwear on his head 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 in the early hours of Wednesday.
His plan fell flat when staff couldn't access any money — with the agitated man fleeing 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.
"Can you help us catch this Captain Underpants caped crusader?" Victoria Police asked on Facebook.
The vision showed the man wearing dark material draped around him like a cape and dark-coloured underpants on his head.
He tripped and fell while fleeing the scene.
Anyone with information was urged to contact Crime Stoppers.
