Three kids from New Hampshire are facing assault charges after police say they attacked, ripped off the mask and yelled racial slurs at Boston's infamous "Keytar Bear" as he played music near Faneuil Hall.

The musician, known to play music and collect tips at popular spots in Boston, was attacked sometime around 4:40 p.m. Saturday, Boston police said.

Officers were called to the area of Congress and State streets for a report of an assault. The "Keytar Bear" was surrounded by a group of young males in what appeared to be a fight.

The males ran when an officer approached in his cruiser with the lights and sirens on. Police said the males tried to escape by climbing up scaffolding.

"The officer was directed by witnesses and bystanders as he pursued the suspects on Water Street toward Devonshire Street, where he ultimately observed three of the suspects climb up the building scaffolding then lay down on a platform in an attempt to hide from police," Boston Police said in a news release. "The officer ordered them from the scaffolding platform, and the suspects complied."

The three juvenile males from New Hampshire are accused of attacking the musician and ripping off his mask. They allegedly struck him several times and yelled out racial slurs, police said.

"When witnesses attempted to intervene the suspects, hurled racial epithets at them before fleeing from the police," authorities said.

The musician identified all three of his attackers, police said. The males were charged with assault and battery, affray and disorderly conduct. One of the males was also charged with being a minor in possession of alcohol when a small bottle of vodka was found in his pocket, police said.

The Boston Police Civil Rights Unit continues to investigate.

The "Keytar Bear" was also attacked in 2014. Two people were arrested at that time.
