GRAYSON COUNTY, TX -- The Grayson County Sheriff's Office has released video of a man they say robbed the Shamrock station in Pottsboro Wednesday.

The sheriff's office is looking for this man. They say he came into the store on Highway 289, Wednesday around 3 p.m, and stole lottery tickets.

Lieutenant Rickey Wheeler says the suspect told the clerk on duty he had a gun but did not show it. The clerk did not back down.

"The clerk eventually struck the man in the face one time, he looked very startled on the video and then uh took a few more lottery tickets and then left on foot," said Lieutenant Wheeler.

The suspect is a black male, in his mid 20s, with a medium build. If you recognize this man, call authorities.
