Authorities in the United Kingdom say a couple kept a Polish man captive inside of a shed on their property for more than four years.

The Gangmasters and Labour Abuse Authority said that a raid on the home of 56-year-old Pritpal Binning and 54-year-old Palvinder on Tuesday led to the gruesome discovery, as reported by the New York Post.

Investigators searched the property in Chilworth and allegedly found the “frail” man in his 40s who said he had been held prisoner in the gardening shed and served expired food.

“He also said that he had no flushing toilet and that his kitchen was a fridge and barbecue,” an agency spokesperson said.

After the suspects’ arrest, the alleged victim was admitted into the care of a government-sponsored program for victims of human trafficking and slavery.

According to Tony Byrne, a senior investigating officer for the authority, the unidentified man is “receiving the help and support he so desperately needs.”

The official went on to decry what is being described as modern-day slavery.

“In the 21st century, no one should be forced to live in such degrading and disgusting condition,” Byrne said.

Following their arrest, the suspects were released as the investigation into the allegations against them continues.

As Fox News reported last month, a 79-year-old British man was arrested in Cumbria for similar charges allegedly spanning four decades.
