TWINSBURG -- Do you know this man?

The Summit County Sheriff's Office has released surveillance video of a man responsible for robbing a Speedway gas station in Twinsburg on Sunday.

The suspect entering the gas station in the 7900 block of Darrow Road around 8:15 a.m. He approaches the counter and presents a large knife.

Authorities say he proceeded to demand cash before reportedly threatening to harm the cashier if she did not cooperate with his demands.

Video shows the suspect walking away from the counter when another employee emerges from a back room. He fled the scene in a white SUV.

The entire incident was less than 30 seconds long.

Authorities say this same suspect may also be responsible for a robbery earlier that same day at a Circle K on North Mantua Street in Kent.

Anybody with information is asked to contact the Summit County Sheriff's detective bureau at 330-643-2131. Anyone who provides information leading to an arrest in this case may be eligible for a reward.
