The Grayson county sheriff's office says undercover narcotics officers in two different vehicles began chasing a suspected drug dealer in Sherman around 4:00 this afternoon. The brakes went out in one of the county vehicles causing the officer to swerve and crash into the Sherman VFW on Frisco road. The officers then got in a second car and continued chasing the suspect until the suspect's vehicle collided into the officers. The suspect ran on foot but didn't get too far before he was arrested. The suspect is a male; his name has not yet been released.
