On May 17th 2014, Debbie was sentenced to 6 years in prison for campaigning against Huntingdon Life Sciences, Europe’s largest animal testing laboratory which kills about 500 animals every day. She was also given an Anti Social Behaviour Order which means she can be arrested if she protests against or contacts Huntingdon Life Sciences (HLS) or its business partners for a further five years after her release from prison.

In April 2017 Debbie was released from prison to "probation hostel" where she has to stay between 1-6 months. She will remain on strict license conditions (probation) until 2020.
