A 30-year-old man was arrested early Tuesday morning in Windsor, Ont., as part of a nationwide criminal investigation.

Local police raided three Windsor residences as part of a cross-county, joint−forces criminal organization investigation called Operation Marvel, Windsor Police spokesperson Sgt. Brett Corey said.

More than 900 police officers on Tuesday carried out sweeping pre-dawn raids mostly in Ontario but also in B.C. and Alberta, alleging murder, drug trafficking and other criminal offences.

According to Corey, the Windsor homes raided were at:

  • 1309 University Ave. W.
  • 315 Josephine Ave.
  • 725 St. Luke Rd.

Windsor Police executed search warrants at all three locations. They were looking for weapons. However, in a media release, police said none were seized as a result of the raids.

The arrested male was found at 1309 University Ave. W.  He has been transported to Toronto where he will face weapons-related charges.

A 55-year-old man was arrested at 315 Josephine Ave. However, he has been released pending further investigation.

No one was found inside the St. Luke Road residence.

Police said in the release that more arrests are possible pending further investigation.

Corey said Toronto Police spearheaded the operation, which began in May 2011. Windsor Police became involved in August.

Corey had few details about the massive operation.

"The information I have is that it was a criminal organization investigation involving exactly that, a criminal organization," Corey said.

At least five Ontario police services were involved in the operation. The investigation involved criminal organization offences, attempt murder, firearms trafficking and importation, drug trafficking, robbery, shootings, prostitution and other criminal offences.

"It pretty much covers the board," Corey said.

An Essex County OPP spokesperson says their detatchment was not involved.
