Saskatoon Police say four men have been arrested in an investigation spanning Saskatoon, Moose Jaw and Calgary.

On December 5th, police received a report from an individual that three men had pointed a gun at him and threatened him with violence.

The investigation led police to believe the same men had committed a robbery in Moose Jaw one day earlier and were conspiring to commit another robbery in Saskatoon on December 6th.

Later that same day, officers arrested one of the three suspects while two more were believed to have fled to Calgary.

Two suspects were arrested on December 24th after a brief evade police incident as they tried to re-enter Saskatoon.

A fourth suspect was arrested on February 11th in addition to police seizing several weapons.

The items seized include a Honcho 12-gauge shotgun, MP40 .22 rifle, SKS 7.62 x 39 long gun, 24 rounds of SKS ammunition, three empty stripper clips, handgun, knife, bear spray, zip ties and rope.

All four men, age 33, 27, and two age 22, are facing an assortment of charges relating to weapons, conspiring to commit robbery, evading police, and intimidation of a justice system participant.
