Surveillance video was released from a robbery at Ready to Go.

WATCH: Man with knife robs market

The Montgomery County Sheriff's Office is investigating the crime.

The man was caught on camera brandishing a knife as an employee at the market closed for the night around 10 p.m. on Aug. 3.

The suspect reportedly told the clerk to give him the money, and threatened to "gut" him if he did not, according to a report from the sheriff's office.

The suspect then used the knife to cut the phone lines, according to the report.

The man fled. He was described as a white male, about 5 feet 8 inches tall and between 140 and 150 pounds. He was wearing black gloves and his face was covered with a black shirt with white and red designs on it, according to the report.
