TORONTO – A Pittsburgh man is facing charges after driving through several communities with a knife-wielding assailant clinging to the hood of his vehicle.

Anna Mazzetti, who claims to be the assailant’s girlfriend, told WPIX that her boyfriend, 36-year-old Steve Sutton, became upset after 46-year-old Dwayne Harvard drove her home Sunday.

“He took a cinder block and he was trying to hit the truck,” Harvard claims in a WTAE report. “I said, ‘calm down. You put the block down.'”

Sutton then allegedly brandished a knife and jumped on the hood of Harvard’s SUV as he attempted to drive away. Mazetti was still in the vehicle at the time.

“The guy pulls out a knife about this long,” Harvard explained. “I was in fear for my life.”

A number of police agencies were called in to help stop the car as it drove through multiple communities.

“We did try to stop the vehicle,” Mazetti claimed in the WPIX report. “He got completely violent like he was going to kill us both. Nobody in their right mind would stop the vehicle.” Mazetti added.

Harvard called 911 himself and a dispatcher directed him to an exit where authorities were waiting to interview both men.

Police charged Harvard with simple assault, aggravated assault, reckless endangerment, and DUI according to Shannon Perrine at WTAE. Sutton, however, was not charged and avoided serious injury.
