WEST MELBOURNE, Fla. -- Two men -- including a current employee of the Office Depot store robbed on Tuesday -- are being questioned by detectives after being detained at a traffic stop Thursday morning in Palm Bay.

The two were taken into custody after undercover West Melbourne police -- with assistance from the Palm Bay Police Department -- carried out an 8:30 a.m. traffic stop on a silver-toned Cadillac near the Palm Bay campus of Brevard Community College.

It was not immediately known where the men were headed. Both were handcuffed and taken to the West Melbourne Police Department where detectives are looking into whether the robbery was the result of an "inside job."

"We had some leads yesterday that put us on to them. One of them is a current Office Depot employee," Cmdr. Steve Wilkinson, spokesman for the West Melbourne Police Department, told Local 6 News partner Florida Today. "The message is that you shouldn't underestimate West Melbourne. If you commit a crime like this then we're going to catch you."

The robbery happened just after 6 a.m. Tuesday at the Office Depot located at 1131 W. New Haven Ave.

Police said two masked men wearing gloves and carrying a gun and a knife got into the store before the opening and held three employees at bay, demanding the key to the cash room.

The manager was pistol-whipped and the other two employees bound with tie straps before the robbers fled out of apparent fear police had been alerted, police said. Only a wallet was taken.

The Brevard County sheriff’s SWAT team was called to the site and cleared the building within three hours.

Since Tuesday morning, police have been conducting a manhunt and have been on the lookout for a beige-colored Cadillac. That description was based on witness accounts from the robbery.
