TORONTO — - TORONTO - Police attached to the G20 security detail seized "quite a bit" of bomb-making material when they raided a Forest Hill home at 58 Elderwood Dr. on Tuesday afternoon.
A police source said an undisclosed quantity of ammonium nitrate and unidentified chemicals were found, possibly enough to match the 1995 Oklahoma City blast.
Police said there was now no danger to the community.
Undercover police in an SUV had been parked in the driveway of another Elderwood home since last Thursday, after a friend of the accused apparently notified authorities. Police told neighbours they were on the lookout for burglars.
But on Wednesday, neighbours said it was obvious the focus was on a suspect who appeared to have explosives.
Byron Sonne, 37, faces several charges, including possession of an explosive, possession of weapons, intimidation, mischief and attempted mischief.
He appeared in an Etobicoke bail court Wednesday and was remanded into custody until Saturday.
On Tuesday, heavily armed police surrounded the two-storey home on Elderwood, on the northwest corner of Rosemary Rd., as other officers executed a search warrant.
The home, jointly purchased in 2003 for $880,000 by Sonne and his artist wife Kristen Peterson, remains sealed by police as forensic officers scoured it for evidence.
Neighbour Jan Wilson said she opened the door of her home Tuesday planning to go shopping when she spotted a "huge black SUV over there with a sniper."
"So I walked right back to the house," she said.
Wilson said she moved in about two years ago and never saw much of the couple.
Another neighbour who didn't want to be identified said the couple kept to themselves.
"They seemed like a very sweet couple. Maybe they are," she said.
The woman said she first realized her normally sedate neighbourhood had changed when she went to bring in her garbage bin and spotted a tactical officer armed with a "bloody big weapon."
The arrest of Sonne, a member of HackLabTO, which dubs itself "Toronto's hacker collective" and based in Kensington Market, was posted on the group's site by Leigh Honeywell: "One of our members has been arrested on a number of charges related to the G20. Byron is innocent until proven guilty and as a member of the lab and a friend, we are concerned for him."
Sonne claims on his LinkedIn profile he's a licensed private investigator with his company Halvdan Solutions.
A search with the security licensing branch confirms he has a dual permit, allowing him to be a PI and a security guard.
His site states his experience summary as "I make order out of chaos."
Sonne says his specialties are in computer and network security.
In 2006, Sonne wrote on the blog NCircle in a debate with another writer about hacking: "Destruction can be good."
"I appreciate the role of chaos and anarchy in the universe; we simply can't have order without disorder and vice-versa. There's no way to separate the two, or eliminate one or the other," he wrote.
