Eighteen people are facing numerous drug-related charges after early-morning raids in several central Ontario communities.

Durham regional police say officers executed 22 search warrants Tuesday -- including 16 in Durham Region, two in Toronto and two in York Region -- following a four-month investigation dubbed Project Bermuda.

The other raids were in Bancroft, northeast of Peterborough, and the Kawartha Lakes area.

Investigators say drugs including cocaine, hashish and marijuana were seized, along with $100,000 in cash, a number of weapons, nine vehicles, a trailer and a boat.

Durham police say the investigation began in Feburary after weapons and drugs were found at a home in Oshawa, east of Toronto.

It grew to involve 11 other law enforcement agencies and targeted street-level drug sellers in the region.

The 18 people arrested face a total of 73 charges and police say one other person has been identified but has not yet been arrested.
