Tucson police are seeking the public's help in trying to identify a man believed to be a member of a group responsible for numerous cigarette thefts.

Between Feb. 17 and Sunday, a group has been involved in at least nine thefts of cigarettes from Circle K stores.

The incidents have happened at stores in the 1700 block of West Prince Road and in the 10000 block of East Speedway.

The group has committed as many as three thefts in one day and most recently stole cigarettes from the Prince store on Thursday and Sunday.

About $25,000 worth of merchandise has been stolen.

Tucson police said the thieves enter the store carrying a bag and walk behind the counter to steal cigarettes and liquor. They wear hooded shirts or jackets to hide their faces. Most of the thefts occur in the early morning.

Police released surveillance photos of one of the thieves on Tuesday. Anyone with information can call 911 or 88-CRIME.
