A 20-year-old Baltimore man pleaded guilty to charges stemming from fires and looting during the unrest after Freddie Gray's death, and to an unrelated assault.

Maryland U.S. Attorney Rod Rosenstein announced the plea Friday.

Court documents say Donta Betts tried to set a police car on fire, looted a CVS pharmacy, and lit a roll of toilet paper on fire, placing it atop propane cylinders and squirting it with lighter fluid to try to prevent officers from coming inside the pharmacy during a riot on April 27. The CVS was burned down and has become a symbol for the anger that engulfed the city in the wake of Gray's death.

Gray died April 19, a week after his neck was broken in the back of a police transport van.
