Pinellas Park police are looking for a woman they say tried to rob three stores in one day.

The woman went into the Subway at 7099 66th St N on Wednesday at 10:15 p.m with a knife and tried to rob the store. However, police said she was unsuccessful and fled.

Police said they believe the woman is the same suspect who tried to rob a Circle K earlier that day. They said the suspect propped the door open during the Subway robbery, which is the same thing the suspect did during the Circle K robbery.

Police said the same woman is also believed to have robbed the CVS on 49th Street just one hour prior to the Subway robbery.

The suspect has not been taken into custody. Police said she should be considered armed and dangerous.

Anyone with information about the identity of this suspect is asked to call 911. To remain anonymous and be eligible for a cash reward, call Crime Stoppers at 1-800-873-TIPS (8477) or report online at http://www.crimestoppersofpinellas.org/
