A Florida man was arrested on Tuesday after police said he robbed a bank, grabbed a drink at a nearby bar and returned to the scene of the crime when he heard sirens.

Stephen Daniel Stump, 36, entered a Key West bank on Tuesday at 12:30 p.m. and demanded money, adding that he had a bomb in his backpack, FlKeysNews.com reports. Stump, who is listed as homeless, left with an undisclosed amount of money and made his way to a nearby bar where he stopped for a drink.

"He paid with a $50 bill from the robbery, telling the bartender to keep the change," city spokeswoman Alyson Crean told FlKeysNews.com. "When he heard sirens, he apparently returned to the bank and was apprehended. All of the money was recovered."

Police said a bank employee noticed Stump outside of the window while officers were interviewing witnesses and he walked up, put down his backpack and allowed them to arrest him. He was arrested on felony charges of robbery and falsely reporting an explosive device.
