Toronto man plunges from balcony after police use stun gun during domestic call

TORONTO - Ontario's police watchdog is investigating after a Toronto man was hit by a police stun gun and then plunged from an apartment balcony.

The Special Investigations Unit says the man was injured after police responding to a domestic call used a stun gun early today.

Video from the scene shows a man straddling the concrete railing and later pacing on the balcony as police watch from inside the apartment and down below.

Later, as the man sits on the balcony, an officer discharges the stun gun from the balcony above and the man moves to the edge of the balcony and then plummets to the ground.

Daniel Wright, 42, was taken to Sunnybrook Hospital for treatment but there's no immediate word on the nature or extent of his injuries.

Toronto police would not comment on the incident because of the provincial watchdog's involvement.

The provincial agency says police officers were called to an apartment building at 1765 Weston Rd., in the city's northwest area at about 5:30 a.m.

Two subject officers and five witness officers have been identified by the agency.

The Special Investigations Unit is an arm's-length agency that investigates reports involving police where there has been death, serious injury or allegations of sexual assault.
