Police in London, Ont., have now arrested 15 people in connection with a St. Patrick's Day riot over the weekend that caused an estimated $100,000 damage.

Three of these arrests are for being intoxicated in a public place, and a dozen arrests were for criminal charges, including unlawful assembly, assaulting police with a weapon, obstructing police and resisting arrest, London Police said Wednesday.

The number of arrests rose from 13 on Monday, as officers combed through video, photos and other tips submitted to police.

Two of those arrested after the riot on Fleming Drive — in which officers were pelted with beer bottles and cars were set alight — were young offenders. One 15-year-old was charged with being a member of an unlawful assembly. Another 15-year-old was charged with being a member of an unlawful assembly and two counts of assaulting police with a weapon, according to London Police.  The rest of those charged ranged in age between 18 and 25 years old.

Police say six of the 15 people arrested are students of Fanshawe College.

This comes after the London, Ont., school doled out interim suspensions on Monday to eight of its students for their involvement in the disturbance.

Under the school's student code of conduct, Fanshawe can impose academic penalties on students whose off-campus actions might affect the health and safety of others in the college community.

"Sadly, I must say the actions of some of our students not only endangered themselves but put our emergency responders and our community at risk," Rundle told reporters on Monday. "This is unacceptable. It will not be tolerated. It will not be excused. And we will not have those people as students of this college."

The college is conducting its own investigation and has created a secure email for students to provide photos, video, tips and other evidence.

The London Police Service has already received more than 150 tips via email and phone.
