The City of London, Ontario, is doing all it can this weekend to avoid a repeat of a drunken St. Patrick’s riot that left a residential neighbourhood looking like a war zone last year.

London made national headlines after partiers near Fanshawe College trashed the streets, leaving damaged cars, broken glass and major property damage.

London Police Chief Brad Duncan says officers will be all over the city ensuring things remain calm.

“If the parties start to get out of hand there will be visits from the police, and of course the ancillary charges that would occur as well,” Duncan said.

“Plus RIDE programs will be in full force, clearly we’ve been able to communicate loud-and-clear that we’ll be present and there will be an accounting for individuals that don’t comply with proper behaviour,” Duncan added.

The mob that formed last year hurled objects at officers and even fuelled a massive street fire with furniture, pieces of fences and alcohol.
