York Regional Police say a 28-year-old Toronto man will be charged with first-degree murder after a dismembered body was found Sunday in the basement of a Thornhill house under construction.

"From what I've been told, it was a pretty grisly scene, a very challenging scene for a lot of veteran police officers," Const. Andy Pattenden told reporters Monday morning.

Just after 6 p.m. on Sunday, two men turned themselves in to Toronto police. Shortly after, York police went to a home at 2 Laureleaf Rd. near Steeles Avenue where they found a man's body in the basement.

Peizheng Qiu faces the following charges:

First-degree murder.

Indecent interference with a dead body.

He made a brief court appearance Monday and is scheduled to make another appearance on April 8.

The second man is being questioned by authorities.

Police say there is no threat to public safety and they are not releasing any information about the victim at this time.

It is not yet clear what relationship, if any, the victim had with Qiu.

Neighbours on Laureleaf Road told CBC News they saw multiple body bags being removed from the house by investigators Sunday.

"More than one," one man said. "Not a pleasant thing to see."

Police are also investigating several reports from neighbours that some high-end vehicles, including a Ferrari, were seen parked near the house Sunday.

"If anyone does have any information, please contact our homicide unit," Pattenden said.
