Montgomery County police apprehended a man wanted for possession of a controlled substance after he lost control of his vehicle the night of July 27.

Jonathan Robert Blackman, 27, was driving a 2002 Honda Accord northbound along U.S. Route 15 around 11:30 p.m.

Just south of West Seventh Street, he lost control of the vehicle and ran off the roadway. Police are not sure what caused the accident.

Blackman's car then hit an embankment along the side of the road and rolled over onto its roof.

Blackman fled the scene of the accident on foot. Police from both the Montgomery County and Frederick County Sheriff's offices joined the chase, along with K-9 units and a State Police helicopter.

They tracked him down two-and-a-half hours later near Hood College.

Blackman, a Damascus resident, was taken to the Frederick Memorial Hospital for treatment of minor bruises before being transported to the Frederick County Adult Detention Center.

According to the Montgomery County Sheriff's Office, Blackman has been at large for possession of a controlled substance with intent to distribute.

After the accident, he was also charged with negligent driving, failure to report an accident involving injury, fleeing police and driving with a suspended license. He is being held on a $9,000 bond.
