Four people are facing drug trafficking charges after a traffic stop.

The Regina Police Service says a car with four occupants was stopped on 4th Avenue, near Albert Street, on Tuesday when officers recognized one of the people as wanted on warrants.

Police say a quantity of what is believed to be crystal meth was found in the vehicle, seized and all four people were arrested.

A second search of a 25-year-old man revealed a substance believed to be fentanyl and more crystal meth on a 32-year-old woman.

At the time of the arrest and in a subsequent court appearance, the 32-year-old gave officers a false identification, using the name of a 25-year-old woman who had no involvement.   The 32-year-old was charged with obstruction the next day and the error has been corrected.

RPS says 53-year-old Daryl Main, 41-year-old Jeremy Hill, 25-year-old Jordan Lylyk and 32-year-old Sara Moisiuk are jointly charged with possession for the purpose of trafficking .

Main is facing an additional charge of failure to comply with probation order, Lylyk faces an additional two charges of failure to comply with probation order and possession of a scheduled substance and Moisiuk is charges with a second count of possession for the purpose of trafficking and obstruct a peace officer.

All four made their first court appearance Wednesday and Moisiuk appeared on her obstruction charge Thursday.
