A Trenton man has admitted to attempting to set a police car on fire during a riot in Trenton last year, according to the New Jersey U.S. Attorney’s Office.

Acting U.S. Attorney Rachael Honig says that 29-year-old Kadeem Dockery pleaded guilty to one count of attempting to obstruct, impede, or interfere with law enforcement officers during a civil disorder affecting commerce.

The charges relate to a large-scale protest in Trenton on May 31, 2020, following the death of George Floyd.

The U.S. Attorney says that while the protest was peaceful earlier in the day, violence broke out later that night when people marched down East State Street and began to riot.

Video images from the scene captured Dockery light an explosive device and through it into the open window of a Trenton police vehicle.

Dockery could face up to five years in prison. He is expected to be sentenced on Sept. 21.
