The Town of Tonawanda workplace was evacuated today after coworkers of Paul Kaiser discovered what looked to be a grenade, a day after Kaiser was arrested in Le Roy and charged with having a live grenade in his car.

All workers at the Anderson Equipment Co. had to be evacuated about 8:30 a.m., and Town of Tonawanda police and the Erie County sheriff’s bomb squad were called into action after what soon proved to be a novelty grenade was found in Kaiser’s work space.

The bomb squad searched the entire building before allowing workers to return.

Kaiser, 26, of East Aurora, won’t face criminal charges for the workplace incident but he is being prosecuted in Genesee County after Le Roy police reported discovering a live grenade in his car during a traffic stop.

Kaiser was in the village to visit a girlfriend, authorities said. He was charged with criminal possession of a weapon, possession of marijuana, speeding and driving with a suspended license.
