A judge set bail for two men who were arrested over the weekend during what police described as a "large-scale vehicle takeover" involving illegal street racing in Boston. The takeover ended with a police cruiser being torched by fireworks.

The Boston Police Department said there were more than 100 people involved in the chaotic scene on Mass. Ave and Tremont Street Sunday around 2 a.m.

Julian Bowers, 18, and William Cantwell, 19, were the only two people arrested. Both men are from Rhode Island. They were arraigned Monday in Roxbury District Court.

A not guilty plea was entered on behalf of both men. Prosecutors sought $20,000 cash bail for Cantwell and $15,000 cash bail for Bowers. Instead, the judge set bail at $500 for Bowers and $1,000 for Cantwell. The two teens fist-bumped after hearing the bail amount. 

Bowers denied to comment on the charges outside the courtroom. 

Boston vehicle takeovers

The men were allegedly part of a massive group that coordinates gatherings on social media and in group messaging platforms. They arrive in various locations and use their cars to block off streets to stop the flow of traffic. Prosecutors said drivers perform burnouts, donuts, and illegal street races, often live-streaming the activities.

One officer's cruiser was being targeted by the group, according to police, so he began to drive in circles in an effort to keep people off the vehicle. Several people jumped onto the hood of the cruiser while others were throwing fireworks and other objects. Police said the officer heard explosions and then noticed the cruiser was filling with smoke and sparks.

The cruiser eventually went up in flames and was completely destroyed. No officers were hurt.

"These takeover events are dangerous, intolerable assaults on our police officers and our neighborhoods. We and our law enforcement partners will do all we can to identify and hold accountable anyone involved.  No one should think they can jeopardize public safety in such a brazen manner without consequences," Suffolk District Attorney Kevin Hayden said in a statement.

Part of growing nationwide trend

Bowers was allegedly seen throwing objects at officers and their cruisers. He was charged with malicious destruction of property over $1,200, disorderly conduct, assault and battery on a police officer and resisting arrest.

Cantwell was accused of repeatedly smashing a police cruiser with an orange pole. He was charged with malicious destruction of property over $1,200, disorderly conduct, assault and battery on a police officer and resisting arrest. Police also charged him with drug possession after allegedly finding two packages of marijuana edibles in his bag.

In court, the prosecutor said this weekend's incident is part of a growing nationwide trend that is organized through social media. Groups often come from out of state and move quickly to overwhelm police, a Boston Police Department task force on the groups said.

"These coordinated efforts are designed to overwhelm law enforcement and maximize online exposure. A deliberate disregard for public safety," prosecutor Lea Deacutis said in court.

Bowers and Cantwell, who have an open drag racing case out of Rhode Island, were ordered to stay out of Boston except for legal proceedings and to meet with their attorneys. They must also wear GPS monitoring bracelets when they make bail.

Both men are due in court on November 5 for a pretrial hearing.
