Channel 4 will be repeating an episode of 24 Hours in Police Custody, which follows the mysterious investigation into the disappearance of Ricardas Puisys in Wisbech in 2015.
The "No Body Murder" episode is about suspected murder victim, Mr Puisys, and the five years he spent in hiding from his tormentor.
In 2015, Mr Puisys seemingly vanished, which triggered a murder investigation.
After years of searching and investigating, detectives discovered Mr Puisys living in a wooded area of Harecroft Road in Wisbech.
The well-documented investigation and shocking discovery was captured by Channel 4.
A spokesperson for Cambridgeshire Police said on social media: "There were many twists and turns in the investigation that uncovered a dark world of modern slavery and exploitation.
"The episode will be shown on Channel 4 on Monday, April 8 at 10pm.
"Modern slavery is happening in the county, but we have specialist officers working hard to combat the issue.
"Information from the public is vital in assisting these efforts – please know the signs to look out for and report any concerns."
