17-year-old from Chelsea arrested for allegedly attacking 20-year-old man with baseball bat in park, police say

The victim remained in critical condition Tuesday morning, police said.

A 17-year-old is facing charges after authorities say he assaulted a 20-year-old man with a baseball bat at a Chelsea park, police said Tuesday.

The teen, who was not identified, was arrested late Monday night for the attack at Mary O’Malley State Park, Chelsea Police Chief Brian Kyes said in a tweet.

The victim was brought to Massachusetts General Hospital with life-threatening injuries Monday.

Kyes said Tuesday the victim remains in critical condition.

The reason for the attack remains unclear, he added.

“There is no specific mention of motive at this time,” Kyes said.

The teen was charged with aggravated assault and battery with a dangerous weapon with serious bodily injury and armed assault with intent to murder, according to Kyes.


He will be arraigned in Boston Juvenile Court Tuesday, the Suffolk County District Attorney’s office said.

Police responded to a report of an assault at the park around 11:30 a.m. Monday.

Authorities found the victim was struck near the tennis courts on Commandants Way, officials said. The weapon was tossed in Island End River before the suspect fled the scene, according to police.

A Massachusetts State Police dive team searched for the bat Monday but it is not clear whether it was found.

According to authorities, the suspect was accompanied by a woman during the assault although no other arrests have been made.
