A second man has been arrested on suspicion of modern slavery offences after a man was found living in a shed for 40 years in Carlisle.

The Gangmasters and Labour Abuse Authority (GLAA), supported by Cumbria Police, arrested the 53-year-old man in the north of the city this morning.

He is currently in custody being questioned.

Investigators previously released a 79-year-old British man under investigation after rescuing the worker from a six-foot shed he was believed to have been living in all his adult life.

The potential victim, who is a 58-year-old British man, has been receiving specialist support over the last six months.

GLAA Senior Investigating Officer Martin Plimmer said: “Our priority since we made the initial arrest has been to ensure that the potential victim has been given all the necessary help and support. This was clearly the right thing to do.

“Alongside this, we have ensured that all lines of enquiry have been thoroughly and objectively explored which has resulted in today’s arrest. I would again like to thank my team for their utmost professionalism and dedication in what is a challenging case.

“If anyone who is reading this has any information, however small, please contact us. You will be spoken to in full confidence and could provide us with crucial evidence.”

Detective Chief Inspector Helen Harkins, of North Cumbria Crime and Safeguarding Team, said: “Cumbria Police are working closely with the GLAA to ensure all lines of enquiry are explored.

“We have assisted with the arrests and will continue to support the GLAA investigation in any way we can.”
