A local man was nailed by police after he tried to attack tellers at U.S. Bank with a hammer, the shirtless assailant blasted with pepper spray as he turned on officers.The suspect, Arlan Pinkard, 32, was subdued by police officers as he stood inside U.S. Bank on Chancery Street around 1:30 p.m. Tuesday, a hammer still in his hand. Police hit the suspect in the face with pepper spray after he came toward them when he was told to drop his weapon. The pepper spray, which filled the bank lobby with its vapor, floored the suspect and also left officers, who took him to the ground, worse for wear with mouths and eyes full of the choking substance.
