A quick-thinking service station attendant has outsmarted an armed robber in Melbourne’s north.

The bungling bandit entered the Bundoora business at 3am on Monday, threatening the attendant with a hammer and a knife.

The attendant convinced him to go outside and wait for cash from the ATM.

Once the robber was outside the Plenty Road business, the attendant locked the doors and called the police.

Officers who responded found the offender still standing outside the doors, waiting for his money.

Leading Senior Constable Melissa Seach said no one was injured during the incident and a 22-year-old Bundoora man was assisting police with inquiries.
