A man wanted on a Canada-wide warrant who was caught in Sudbury has a history of sex-related convictions involving children. Over the years Thomas Robichaud underwent failed sex offender treatments including chemical castration. The warrant went out for the 44-year-old for breaching a long-term supervision order. Last December a judge declared Robichaud a dangerous offender. In his most recent case, Robichaud admitted that he had lured a minor online for sex.
