Niagara police arrested and charged four people after seizing over $16,000 dollars worth of illegal drugs.

Officers began an investigation in April into the distribution of illegal drugs throughout Niagara Falls.

Detectives then received permission Tuesday to execute a search warrant in the area of Green Ave. and Rysdale St. in Niagara Falls.

Police were able to seize suspected cocaine, fentanyl, crystal methamphetamine and nearly $2,000 CAD believed to be proceeds of crime.

Forty-eight-year-old Cathy Dennis of Niagara Falls, 53-year-old Candy Stewart of Niagara Falls, 47-year-old Christopher Judge of Niagara-On-The-Lake and 39-year-old Rebecca McDonald of St. Catharines face multiple drug-related charges.

All four suspects have been released and are scheduled to appear in court on Aug. 4.

Anyone with information about this investigation is asked to contact detectives at 905-688-4111, dial option #3, ext. #1022200.
