A New Brunswick family that filmed a trio of teens throwing a flaming cardboard box at their home says the group came back after CTV News aired their story.

Amanda Gilbert of Riverview, N.B. told CTV News a group of teens began harassing her family about six months ago so she decided to take matters into her own hands and caught the latest incident on camera on the weekend.

She had hoped that putting the story, and the video of the teens, in the public eye would put a stop to the behaviour, but she says the teens came back Monday night after the story aired.

"Last night they came back, made a bunch of noise in the woods," says Gilbert. "We were outside, heard them and called 911."

When the RCMP arrived at her home, the teens took off. But Gilbert did receive some good news. The three teens she captured on video have been identified.

"It was a huge relief. Now we can press charges," she says.

But Gilbert says while three people have been caught, the group of teens sometimes approaches 30, and while others have been caught by police in the past, they always seem to be let go.

"The Young Offenders Act requires us to follow certain procedures," says Const. Damien Theriault. "One of them could be to just give a warning to the kids and talk to their parents."

A Facebook group has been formed by citizens determined to help Gilbert when the teens show up at her door. But police are asking citizens not to get involved.

"You never know what the other group might do," says Theriault. "It might be touchy. Do not encourage any type of confrontation."

Gilbert's boyfriend, Pete Crandall, knows firsthand what can happen in that situation. He has had numerous run-ins with the group and on at least one occasion, the confrontation turned physical.

"There was a couple of times I felt for the safety of Amanda and the children, at which point I grappled a couple down to the ground," says Crandall. "Police came and apprehended those kids."

No arrests have been made in the latest incident, but Gilbert says she will continue to rely on her video camera to catch the culprits.
