MONTREAL - Investigators say they have found a knife on the scene of a police shooting where a teenager was wounded in north-end Montreal.

The 18-year-old man was shot in the stomach by police on Saturday after they received information that he was wanted in connection with an attempted murder and he remains in hospital in stable condition.

Police say he threatened them with a knife.

The family, who identified the man as Nashwan Abdullah, told CTV News on Saturday that they disagreed with police claims that the man had a weapon.

By this morning, investigators had finished searching the area and had interviewed 13 witnesses.

Meanwhile, Montreal Mayor Gerald Tremblay appealed for calm in the aftermath of the second police shooting in less than two months in the area.
