Ross Kemp has been forced to halt filming on his World's Most Dangerous Prisons series after running into "an incident".
The former EastEnders star and TV hard man is known for his risky documentary series, but the latest show which would immerse him in some of the world's grimmest prisons has had to take a pause in production.
According to Deadline, Kemp, 59, had already begun filming the series which he promised would "go even further than before" and the team were due to head out to South America for the next leg of the production, which would have taken them up to Christmas.
But the brakes have been put on the documentary following an apparent "incident" while the Paramount+ network hold talks with the producers of Ross Kemp: 72 Hours in...to try to get the series back up and running.
Whatever the incident was has not been specified, but Channel 5, who are due to broadcast the show, have commented on the hurdle they are facing.

A spokesperson said: "Filming had begun on the series, but due to unforeseen production challenges, we have made the practical decision to halt filming at the moment."
Kemp's previous danger-filled documentaries have included Ross Kemp on Gangs, Ross Kemp in Afghanistan, Ross Kemp Behind Bars, and Ross Kemp: The Fight Against ISIS.
World's Most Dangerous Prisons is set to be his first documentary series for Channel 5 and the show's description says that it "goes behind bars in some of the world’s most high-security, high-risk prisons housing gang leaders, serial killers, violent criminals, drug lords and mass murderers".
Announcing the new series, Kemp had said: "I’ve been to some of the toughest prisons in the UK and all around the world. I thought I’d experienced it all, and taken every adventure, but this time we’re going even further than before.
"I’m looking forward to my first documentary series with Channel 5 and taking you all on this journey with me."
The TV star also presents the series Ross Kemp: Shipwreck Treasure Hunter where he dives to some of the world's most fascinating underwater wrecks.
He had apparently planned to take a submarine to the wreck of the Titanic, but his agent said that following the OceanGate sub disaster in June he had decided against the mission as "unsafe".
