London police say they have officially concluded their investigation into a St. Patrick's Day riot.
The three-month investigation ended with 68 people facing a total of 175 charges.
Of those charged, 26 were Fanshawe College students at the time of the incident.
The violence caused more than 100-thousand dollars of property damage and led to a beefed-up nuisance by-law being approved by city council last month.
