Police are still looking for suspects after a young woman in her 20s was found tied up and stabbed to death in her apartment Tuesday evening.

The woman, whose identity has yet to be released, is the city's 46th homicide victim of the year.

Police and other emergency service workers were called to the building at 75 Talara Drive, in the Bayview Avenue and Sheppard Avenue East area, at about 6:30 p.m.

They found the victim in a fourth-floor apartment. She was pronounced dead at the scene.

Police officers escorted a young man, believed to be the victim's boyfriend, with his shirt pulled over his head to a police cruiser outside the building.

The man was reportedly questioned by police for much of Wednesday.

However, police are not saying whether they have suspects in the case.

"We are speaking with people, but at this point we're keeping a very open mind," Toronto police Homicide Det. Sgt. Savas Kyriacou told reporters Wednesday. "We're trying to speak to as many people as we can, we're trying to get to know our victim, get to know who she was and who her friends were and her lifestyle."

Several residents said it was the first time anyone had been killed in the building, located on a quiet street just steps from the Bayview Village shopping centre.

"You don't know when it's going to happen, where it could happen, it's shocking," one resident told CTV Toronto.

However, some residents reported seeing a prowler dressed in black clothing in the neighbourhood in recent weeks.

"I just told police that there's been a peeping Tom in the area," one resident told CTV Toronto.

Another resident told reporters that a neighbour told her he had seen a man looking into windows of ground-floor apartments.

"Obviously at this point I'm going to have to say that everybody in the area should be vigilant," Kyriacou said.
