Toronto police have two teenaged suspects in custody in the fatal school shooting of 15-year-old Jordan Manners.

A 17-year-old boy was apprehended on Sunday and charged with first-degree murder after emergency task force officers swept down on a number of residences in the city's west end.

That suspect is to appear at the Finch Avenue courts on Monday.

Police had been seeking a second suspect who had been considered armed and dangerous. The 17-year-old youth turned himself into police late Sunday night. No court appearance date is yet available for him. He also faces a first-degree murder charge.

"Yes he has turned himself in," said lawyer Alana Barnes. "That's all we have to say at this time; no other comment. He's in custody and he's safe."

Neither youth can be identified under the Youth Criminal Justice Act. Both are from Manners' neighbourhood.

CTV's Denelle Balfour said the police took the unusual step of getting a court order allowing them to temporarily publicize the identity of one suspect.

"Within a few hours, the young man turned himself in. He was with his parents; they were obviously upset," she said.

Investigators remained tightlipped about the raids on Sunday. A news conference is scheduled for Monday.

A Manners family member declined to comment Sunday evening.

"We have no comment for the press right now," a woman who identified herself as the boy's aunt told The Canadian Press. "The police have not spoken to us -- we do not know anything."

Manners was gunned down on the second floor of C.W. Jefferys Collegiate Institute on Wednesday afternoon. The shooting prompted a four-hour school lockdown.

The gunman fled the scene and no weapon was found. Police did not release a description of the suspect, but said they anticipated a quick arrest in the case.

Manners' mother Lorraine Small watched as police officers made a number of arrests on Sunday. Residents shouted at police and reporters, saying the wrong people were being apprehended.

One boy taken into custody was one of Manners' good friends.

"Jordan was like a brother to him," Small said.

Forensic investigators searched a number of residences and carried out bags of personal belongings.

Police had warned residents in the victim's Jane-Finch neighbourhood not to hide the shooter, and called for anyone with information to contact police.

On Friday night, police brought in a teenager for questioning. That teen was believed to have been an accomplice in the shooting.

Police have not yet commented on a possible motive for the slaying.

A visitation for Manners will be held on Tuesday and Wednesday, while the funeral is set for Thursday.

Classes at C.W. Jefferys are set to resume on Monday.
