In Oshawa, two teenagers attacked a man with a knife with whom they had arranged to buy a Moose Knucles jacket.
Durham police said they received a report of the robbery at about 3:30 p.m. Monday.
The victim of the attack, a man, had placed an ad for a Moose Knuckles brand jacket and arranged to meet two teenagers. While one of the buyers was measuring the jacket, the other stabbed the seller and both teens fled the scene.
With the help of K-9 dogs, the perpetrators were found very close to the crime scene. Investigators report that the dog bit one of the robbers.
The seller of the jacket was taken to the hospital, his life is not in danger.
The Moose Knuckles jacket is priced between $600 and $1,000 in stores.
Two teens, ages 15 and 17, were arrested and charged with robbery and armed assault.
The police have issued special recommendations for safe online sales: do not go to such meetings alone, and try to hold them during the day, in places where there are a lot of people. Not so long ago, the police issued similar guidelines to prevent parcel theft.
