Buffalo police are seeking a suspect, possibly in his teens, who robbed the First Niagara Bank branch in the 500 block of Elmwood Avenue near West Utica Street just before 12:30 p.m.
He ran out with an undisclosed amount of money.
Police spokesmen said the suspect, described as a black male about 6 feet, 1 inch tall and weighing about 180 pounds, was wearing a white and blue Yankees baseball cap and shirt.
The suspect handed a teller a note threatening to use a weapon that was never displayed before he ran out. Anyone with information is asked to call or text the Police Confidential TIPCALL Line at (716) 847-2255 or email the department through its website at www.bpdny.org
