He faces four charges, including first degree murder of a law enforcement officer and carrying a firearm without a license. Holt has been identified as the person who shot and killed Officer Brian Shaw.
Holt was arrested early Tuesday morning and is being held without bail at the Westmoreland County Prison. Police have said Holt was a passenger in the vehicle and shot the rookie officer in the chest while he was chasing Holt on foot.
State police are offering more than $50,000 for information leading to the arrest and conviction of Holt. The Pittsburgh Tribune-Review also said several associates and Holt family members were charged with hindering apprehension.
Holt has been in and out of jail on drug and assault charges.
The man accused of fatally shooting a rookie police officer in western Pennsylvania was taken into custody Tuesday, the state police said.
