ST. CATHARINES, Ont. -- Police say eight people are facing charges following a six-month investigation into an alleged drug ring in Niagara Region that investigators say has ties to the Greater Toronto Area.

They say the investigation -- dubbed Project Icarus -- began in March and uncovered evidence of a large cocaine trafficking ring based in the Niagara Region.

Approximately 110 officers executed 13 search and arrest warrants early Wednesday in Welland, Port Colborne, Fort Erie, Oakville and Niagara Falls.

Police agencies involved in the operation included Niagara Regional Police, Canada Border Services Agency, provincial police, RCMP and Halton police.

Those arrested range in age from 33 to 41 and were to appear Wednesday in court in St. Catharines, Ont., facing drug-related charges.

Investigators said they expected to release further details of the operation later Wednesday.
