Monroe County Sheriff's deputies are looking for a suspect who they say robbed the M&T Bank on Panorama Trail in Penfield.
Deputies say a man, who they're only describing now as having a large frame, walked in and demanded large sums of cash. They say he did not display a weapon.
The dye pack in a bag he was carrying went off, and deputies believe he is covered in red ink. They think he may be seeking medical attention.
The Sheriff's Office is asking anyone with any information to contact 911.
