Police say an Ohio Salvation Army bell-ringer outside a Kmart store was robbed of his red kettle by four men with a knife.

North Canton police say they don't know how much donated money was in the kettle when it was taken Saturday evening.

Police Sgt. Frank Kemp tells WJW-TV the four men, all wearing dark clothing and hoodies, threatened to use the knife. Kemp says the bell-ringer followed the Salvation Army's standard procedure in such cases and did not put up a struggle. The robbers took off on foot.

Police are asking for tips to help find them.
