The Ulster Boxing Council, the Irish Athletic Boxing Association (IABA) and the Northern Ireland Prison Service jointly hosted the six-week, non-contact boxing course for Hydebank prisoners.

The course included professional advice on diet and nutrition, mindfulness and mental health.

Justice Minister Naomi Long said: “Many young people come into custody because they have lived chaotic lives and made bad decisions.

“This course has not only helped these individuals build their physical strength, but it has made them feel mentally stronger, which in turn helps them to deal with the challenges life will bring them.

“Sport can also instil a sense of achievement which builds confidence and self-esteem, necessary if these young men and women are resettling back into the community.”

She added: “Carl and Paddy are great role models and I want to thank them for taking time to talk to the young people who have taken part in the programme.

“The work of prison staff, along with their partners in the Ulster Boxing Council and the IABA are helping to support and challenge the people who have taken part to change. I look forward to seeing this initiative being rolled out across our three prisons.”

Speaking during his visit, Mr Frampton said: “Boxing has given me everything I have and I am always grateful to be able to give something back to the community. When I was growing up in Belfast boxing gave me a sense of purpose and it is great to see the people here involved in such a great sport.”

Mr Barnes added: “I think boxing can teach these young people skills that can help them in the next part of their lives. I learned a lot from boxing by listening to my coaches and working hard and I’m sure it has been the same for the people taking part in this programme.”

Fergal Carruth, CEO of IABA, said: “This has been a great initiative by the Prison Service and we are delighted to be part of it.

“It has been a tough six-week programme but I know that each of the participants has taken a lot from that. Boxing is at the heart of many communities and it is great to see it is now part of this community.”
