Three more people have been arrested in connection to Project Road King.
Last week, police arrested 39-year-old Keir McColl of Ancaster, 32-year-old Tudor Sopterian of Hamilton and 43-year-old Dejan Zlojo in connection to the large scale investigation that saw 30 others arrested in September.
Charges range from unlawfully producing fentanyl to intimidation, with a fourth suspect still wanted in the investigation. The three suspects arrested last week remain in custody.
Niagara Regional Police says more charges are anticipated as Project Road King is an ongoing investigation.
