Vancouver police Tasered a man Friday afternoon while responding to an altercation on the Musqueam Reserve.

According to police, officers were called to a home in the 6500-block of Hum-Lu-Sum Drive about 5:20 p.m.

Two intoxicated brothers -- one 47, the other 34 -- had gotten into a fight and the older one allegedly stabbed the younger one in the shoulder with a knife.

Officers confronted the suspect outside a nearby home with their guns drawn. The man allegedly refused to obey their commands and approached the officers.

The man was Tasered once and taken into custody, police said.

Police said the man was taken to hospital for checkup. He faces charges of possession of a dangerous weapon and assault with a weapon.

The victim was treated at the scene. A large butcher knife was recovered by police.

The manufacturer of Taser guns recently issued a training bulletin recommending that officers avoid firing at the chests of suspects.

The bulletin said it was not possible to predict or test whether Tasers do or don't affect the human heart.

Const. Jana McGuinness told Friday night that she did not know where on the body the suspect was hit.

Vancouver police have said officers are aware of the bulletin.

Tasers came under scrutiny after a Polish immigrant, Robert Dziekanski, died after being hit by a Taser at the Vancouver International Airport in 2007.

An inquiry into his death recently concluded and a report should be ready in 2010.
