Several of the men arrested in connection with a pedophile ring worked with children or had prior charges of child pornography.

Thirteen men were arrested and charged after Quebec and Ontario police busted an online pedophile ring on Wednesday.

Two of the men, Claude Paquette and David Turcotte, volunteered as group leaders for the scout troupe Adventurer Association of Baden-Powell.

It's not clear if the two men knew each other, Nicolas Rousseau, vice-president of the association, said.

"We're very shocked. Personally, I don't know this person, but they took all the necessary steps to be animators," he said, referring to background checks and other forms.

Neither were the subject of complaints from parents or kids, and both are no longer allowed to volunteer, he said.

"We work with the most precious things of these parents. We work hard, we believe in what we do. We hope that parents won't stop having confidence in us," Rousseau said.

This is what is known about some of the suspects.

Paquette has been a Grade 3 Teacher at the École Primaire Île-des-Soeurs in Nuns' Island since last November. Parents at the school have been alerted to his arrest and he has been suspended with pay.

"Until now, there had been no complaints about him within the school board," said Barbara Blondeau, a spokesperson for the Marguerite-Bourgeoys school board.

The school board is offering psychological counselling to students, parents and teachers.

Parents of students at the elementary school said they were stunned by the news.

"I'm just really shocked...it's really shocking," said Sahar Soodbakhsh, the mother of a Grade 1 student.

"You're just not feeling safe when you find that maybe something happened like this in a school, but I feel we are in a century where this is happening everywhere. So we have to [warn] our children about these problems." 

"I feel sad for the kids. But I'm very confident that the school did everything they needed to do...He hasn't been there for a long time — just three months," said Isabelle Legris, the mother of a child in Grade 2 who said she didn't know the teacher. "I feel very good now that he's not there anymore."

Paquette was also a teacher in Saskatchewan and elsewhere in Quebec. He was charged with production and distribution of child pornography.
