Frederick Raphael Mayorga, 19, was arrested for allegedly barreling into Sgt. Patrick Kepp just after 3:45 a.m.
Mayorga was reportedly known to provoke officers into chasing him, so when he was spotted doing doughnuts, wildly getting on and off the highway, swerving and speeding up to 110 miles per hour, officers did not pursue the vehicle. Instead, they set up along the interstate from Clarksburg to Rockville.
"He intentionally struck Sgt. Kepp in the main lanes of I-270," Montgomery County Police Chief Marcus Jones said at a press conference. He added that Mayorga continued speeding down the highway until his vehicle was disabled by spikes laid out by another officer, Fox reports.

Frederick Raphael Mayorga, 19, faces an attempted murder charge.
