A robbery suspect in Fall River was tracked down by the men he allegedly robbed, and held until police arrived.

The incident happened Friday about 10:30 p.m. outside Royal Pizza on North Main Street.

According to police, a man wearing a mask and armed with a handgun approached three men standing outside the store and demanded money. He threatened to shoot them if they called police.
