A violent home invasion in Gatineau this weekend has police warning people to be careful opening their door to strangers. Gatineau police are looking for two men after a couple was terrorized by the intruders. A simple knock on the door turned a Saturday evening into a nightmare for a couple in their 60s who were tied up, cut and robbed. It's a wake-up call for many of us who blindly open the door to be polite.

Two days after they were robbed at knifepoint in their own home, the homeowner is still answering the door to strangers.

“Il m’a donne un coup de couteau,” says the husband, who is clearly shaken and injured by the events.

They tied me up and cut my back and legs, says the husband.  His wife was treated in the hospital for shock after a violent home invasion around 6:30 Saturday evening.

“For sure, the motive is theft,” says Lieutenant Jean-Francois Beauchamp with the Gatineau Police.

Police say one man knocked on the door in the quiet cul-de-sac on Rue Cartier in Gatineau and asked to use the phone.  The woman let him in but a second man charged in as well.

"They took the woman victim and tied her hands with rope,” says Beauchamp, “and they put that woman, the victim, in another room in the house but the husband, they fight with the suspect, tied his hands.”

In the course of the struggle the husband was cut. The two men robbed them and fled. 

The woman managed to get out of the house.  With her hands still bound, she ran to the neighbours’ house right next door. Together, they called police.

Police are now looking for two French-speaking men in their 30's. One is described as Caucasian, 6 feet tall with a muscular build.  The other is about 5 feet, 8 inches, also Caucasian.

"I’m afraid now,” says resident Neomie Ledoux, who says there are only a handful of houses along the street and that everyone knows everyone. “Before it was always quiet, it's the first time and we never know if it will happen again.”

But it is happening on this side of the river as well. Now Ottawa Police are warning people to be wary of who is at their door. 

"You have a peephole or a window,” says Constable Chuck Benoit with the Ottawa Police, “you don't always have to open the door, you don't always have to be polite to everybody at your door and it's not being impolite to ask who it is, it's be cautious and safe.”

Constable Benoit says if someone asks to use your phone offer to call for them.  If charities are collecting, ask to see their credentials, through a window.

The police say that advice is especially important for kids home alone after school.  They should never be answering the door.  It should stay locked until the parents come home.
