Three males and one female are facing drug- and weapons-related charges as the result of an investigation by the Thunder Bay Police criminal investigations branch.

In a release issued early Monday morning, police said two high-risk vehicle stops and a search of a residence involving Thunder Bay Police Emergency Task Unit have resulted in the seizure of weapons, drugs and cash.

The traffic stops and residential search all took place on Thunder Bay's north side on Sunday evening, but specific locations weren't available.

The weapons included four loaded handguns and two loaded shotguns, police said.

Few other details were available Monday, but police said all four suspects have ties to the Ottawa area.

Their names and ages haven't been released yet.
