Police say David Willis didn't take well to a security guard's attempt to stop him when he ran out of wearing a pair of stolen sneakers on Wednesday.
Willis, 41, walked into the Boston Post Road department store at noon, slipped his old sneakers off, donned a new pair of sneakers from the store and headed out past the cashiers, Lt. James Ladeairous said.
When a store security guard tried to stop Willis, the Port Chester man turned around and snapped at him.
"I'll cut you!" Willis threatened, according to witness statements given to police.
The security guard backed off and dialed police as Willis ran, but Willis didn't get far. After police issued a description of the suspect over the radio, D.A.R.E. Officer Melissa Acocella spotted Willis on South Regent Street and took him into custody.
Without the threat, Willis would have been charged with petty larceny, a misdemeanor. But the threat elevated the charge to third-degree robbery, a felony.
Willis, of Willow Street, was arraigned and scheduled to return to Port Chester village court.
