The Winnipeg Police Service is reminding Winnipeggers to be cautious when buying or selling items online. 

Police say between Nov. 4 and 5, officers responded to two similar reports involving a robbery with a firearm. 

During both incidents, the victims visited a home in the St. Matthews neighbourhood to purchase a cell phone offered in an online ad.

When the victims arrived at the residence, they were robbed of their money at gunpoint by two suspects who then fled the area. 

Neither victim was injured, and they did not get a cell phone. 

The suspects are described as two adult males with dark skin.

No arrests have been made, and the Major Crimes Unit has taken over the investigations. 

Meanwhile, the Winnipeg Police Service says when buying or selling online, it is important to find a safe place to make the transaction, including one of the four Buy and Sell Exchange Zones, located at each of the four Winnipeg Police Service Stations in Winnipeg. 

They also encourage people not to meet up with someone alone and to complete the transaction during daylight hours in a public space. 

Anyone with information on these incidents is asked to contact the investigators at 204-986-6219 or anonymously at Crime Stoppers 204-786-TIPS or winnipegcrimestoppers.org
