REVERE (CBS/AP) — Nine people face charges after a huge brawl involving more than 100 people on Revere Beach over the weekend.

State Police said the melee was apparently sparked by a group of young people drinking and perhaps smoking marijuana and disturbing nearby families early Sunday evening.

State Police spokesman Dave Procopio told WBZ-TV troopers had to move in to disperse the group. As they began to confiscate the alcohol, soda bottles were thrown at troopers.

Procopio said a couple of the kids jumped on troopers’ backs as they were trying to clear people out of the area.

Transit Police, Revere Police, and officers from several neighboring towns were called in to help.

Witnesses told WBZ-TV the fight initially started after a woman’s purse was allegedly stolen and that escalated into multiple fights.

At one point, a woman allegedly punched a police officer.

“Once the girl punched the officer, that’s when I got scared because everybody that was sitting over here started coming off and into the crowd with the police,” said witness Nicholas Stevenson.

Procopio could not confirm that an officer was hit.

There were no reports of any serious injuries.

Five women and four men people were arrested, all of them charged with disorderly conduct. Procopio said 8 of the 9 arrested were juveniles.  The lone adult was identified as Cornelius Jackson.

State Police will increase patrols at Revere Beach, by adding several uniformed and undercover troopers, as well as a K-9 unit.

“The increased presence will begin this Friday, May 15 and will continue on all warm weekend nights up to Memorial Day. From Memorial Day on, the increased patrols will work every weekend night through the summer,” Procopio said in a statement Monday.
