Overview
- Sheffield Crown Court imposed a life sentence with a 10‑year minimum term, with the judge saying it would likely never be safe to release Trennan.
- Trennan pleaded guilty to aggravated burglary, possession of a blade, trespass with intent to commit a sexual offence, and remaining unlawfully at large.
- In July last year he followed a female student into her Sheffield home while armed with a knife; she disarmed him and fled, and he was arrested in York three days later.
- The court heard he had admitted being aroused by violence, and prosecutors described him as exceptionally dangerous while securing admission of bad‑character evidence.
- Trennan previously received life sentences for a 1991 Sheffield rape and a 2002 Norwich attack committed after escaping during day release.
