Saskatoon police have released photos of two men suspected of being part of a crew that robbed a Birks jewellery store in February.

Canada-wide warrants have been issued for Pierre Louis Hernandes and Rida Niam. Both are wanted on charges of armed robbery, wearing a disguise during the commission of an offence, conspiracy to commit arson and breach of probation.

The robbery happened over the noon hour on February 1 and was caught on the jewellery store's surveillance cameras.

Four men came into downtown store with crowbars and smashed display cases. They made off with bags full of Rolex watches and jewellery.

Since then, one of the suspects has been caught. Muhidiin Ahmed-Farah was arrested in Montreal and returned to Saskatoon.

He pleaded guilty to a range of charges and was sentenced to four years in prison.
