The Saskatoon police drug unit have charged three people in connection to a trafficking investigation.

On Thursday, police arrested a 28-year-old man and a 24-year-old woman in a parking lot in the 600 block of University Drive. Officers had started investigating the man in July after he was suspected of trafficking methamphetamine.

Police said they found a small amount of meth in the vehicle. Later, they searched a house on the 300 block of Cumberland Avenue S. and found guns, a machete, more than $3,300 in cash, 19 hydromorphone pills, cocaine and 88 grams of meth.

Officers said they also found items commonly seen in drug trafficking operations.

A 39-year-old man in the home was charged with meth possession and breach of conditions.

The 28-year-old man is facing four drug trafficking and possession charges, along with 13 weapons-related charges. He's also been charged with possession of property obtained by crime.

The 24-year-old woman in the car has been charged with meth possession and breaching her conditions.

Three other women were arrested at the home but were released.
