DALLAS (CBSDFW.COM) – Authorities have released surveillance video from a robbery at a North Dallas GameStop in the hopes of identifying a suspect who has hit three area businesses in less than a month.

The suspect was caught on tape demanding a clerk put money from the register into a bag on Nov. 3 at a GameStop location at 6031 Forest Lane.

The suspect is believed to be the person who robbed another GameStop on Oct. 7 at 5931 Greenville Ave. and a Tom Thumb gas station at 14949 Preston Rd. on Nov. 2. Detectives did not indicate that video footage was available from either of those incidents.

Investigators are asking anyone with information about the man to call the department’s robbery unit at 214.671.3649 or Crime Stoppers at 214.373.8477. All tips are anonymous.
