Westport Police are looking for a suspect who robbed the CitiBank on  Post Road West Friday afternoon.  Police say the man showed a knife with a black handle, and passed the teller a note demanding money.

He fled on foot westbound into Norwalk.

Police describe him as about in his late thirties to early forties, six feet tall with a muscular upper body,  wearing a long black trench coat, blue hat with orange writing. Police found evidence from the robbery — including the trench coat — about a mile from the holdup.
