Northampton Police are looking for a man accused of stealing money from a Girl Scout cookie sale.  The girls were set up in the lobby of the Northampton Walmart around 8 p.m. on Saturday when a man grabbed their metal tin.  He ran outside where an escape vehicle was waiting.  A dad gave chase, got his hand caught in the vehicle's window and got dragged across the parking lot before he could free himself.  He's expected to be OK.
