A 23-year-old D.C. man was charged Thursday with arson and explosives offenses for throwing a Molotov cocktail at an occupied police car in Northeast, according to federal prosecutors.

The criminal complaint alleges that Ashton Nesmith walked toward an MPD officer as he was parking an unmarked cruiser near the Sixth District police station around 5:50 p.m. on Wednesday, then lit a molotov cocktail and threw it. The device bounced off the vehicle and exploded on the ground nearby, and the officer wasn’t injured, according to prosecutors. They allege that Nesmith ran from the scene, but officers pursued and apprehended him.

“This was a callous attack on law enforcement with potentially disastrous results, and we are grateful that the suspect is in custody,” ATF Washington Special Agent in Charge Ashan Benedict said in a statement.

Nesmith has been charged with arson, using and discharging a destructive device during a crime of violence, and possession of a destructive device. He appeared in U.S. District Court on Thursday and was ordered to be held without bond, according to the U.S. Attorney’s Office. He faces a minimum of 35 years in prison.

“The charges filed in this case should serve as a warning to anyone who would consider resorting to violence against law enforcement or anyone else as we face the current health crisis,” U.S. Attorney Timothy Shea said in a statement.

D.C. Fire and Emergency Medical Services responded to a similar incident on April 12, when officers found a smoldering molotov cocktail between two MPD cruisers in the Sixth District station parking lot, thrown from over the fence, according to D.C. police reports. The device didn’t explode and was put out with a water can. Police are still investigating the incident.
