A serial sex offender who had recently moved into a Brampton neighbourhood, sparking outrage from Mayor Patrick Brown, is back in custody after a long-term supervision order was rescinded.

Last Friday Peel police issued a rare public safety warning after learning that Madilyn Harks, who has been convicted of sexually assaulting girls under the age of eight three times, was moving into the Main and Queen streets area.

“Harks’ young victims have included neighbours and a fellow member of a church congregation,” police said in a release.

Police said Harks, 36, was at “an elevated risk to re-offend” prompting Brown to pen a letter to Minister of Public Safety, Ralph Goodale, calling Harks’ release into the community “unacceptable.”

“…this monster has claimed to have victimized 60 girls,” Brown wrote. “The fact that Ms. Harks is in a half way house instead of jail is a clear example (that) our justice system is broken.”

On Friday, Harks was back in custody after Peel police enforced a warrant of suspension revoking the Long Term Supervision Order that Harks was bound by.

Brown’s office says Harks was back in custody after violating her parole conditions.

CityNews has reached out to Correctional Services Canada for more details, but hasn’t yet received a response.

Brown celebrated the news on Twitter, saying “This serial pedophile is no longer a threat in our City.”
