Moment ex-Russian spy Sergei Skripal caught on CCTV feeding ducks with kids and has no idea he's been poisoned

This is the moment a former Russian spy handed children bread to feed the ducks after he had been poisoned with a deadly nerve agent. One boy fell ill after coming into contact with Sergei Skripal the day he and his daughter Yulia were contaminated with deadly novichok. CCTV footage shows Mr Skripal talking to the child and handing him bread to feed the waterfowl in Salisbury, Wilts . The CCTV footage features in the forthcoming Channel 4 documentary Salisbury Poisonings: The Untold Story. It shows Sergei and Yulia Skripal on March 4 2018 close to where they would be found slumped on a bench unconscious. Novichok had been left on the front door handle of their home and they are thought to have become contaminated after leaving the house. CCTV footage showed them then driving into Salisbury, handing the boy bread to feed the ducks, having a drink in The Mill pub and then heading to Zizzi restaurant. Tracy Daszkiewicz, former Wiltshire director of public health, told the documentary: "If they were contaminated for all of this walk how many people around them were at risk? "You think about the people who had been at the restaurant at the same time, at the bar at the same time. But then as we were working through the timeline one of the places that was shared with us was the river and there was an image on CCTV and Sergei and Yulia feeding ducks. "The CCTV also showed Sergei sharing bread with children who are there feeding the ducks so have they been affected? We have to get the children checked but how do we find them? "And of course we knew what the substance was and how dangerous it was so you do think how can anybody survive it so you are worried and there's just the recklessness of it. How does it happen? And how does it happen here? It's just a sense of disbelief." The boy, along with two others, was later traced as part of the investigation into the Russian attack, and reported being ill for a day or two after the incident. But the Dawn Sturgess inquiry heard no traces of the deadly nerve agent were found on the children when they were eventually tested. The three-part Channel 4 series tells the story of the poisoning of former Russian double agent Skripal and Yulia. Det Sgt Nick Bailey was later sent to Mr Skripal's home where he was contaminated after touching the door handle of the home. Just months later, Dawn Sturgess, a British mother-of-three, tragically died after accidentally coming into contact with the same poison. Detective Inspector Ben Mant of Wiltshire Police tells the programme he still feels "a responsibility for what happened" after making the decision to search the Skripals’ home with Sergeant Nick Bailey who nearly died. Mr Mant said: "When we got to the front door Nick and I were stood next to each other and I asked Nick to check the handle so he gave it a good yank. "As the day went on Nick became increasingly poorly and started to hallucinate and ended up in intensive care. We didn't know whether or not he was going to survive." Mr Bailey came to a financial settlement with Wiltshire Police after suing them over the incident. A global warrant is out for the arrests of three Russian agents - Alexander Petrov, Ruslan Boshirov, caught on CCTV, and Sergey Fedotov - but Russia will not extradite them. Former Counter Terrorism Police chief Neil Basu has claimed that a senior civil servant responded to Dawn's death by saying: "Thank god it's a drug addict". Mr Basu said: "I remember looking at the DG of MI5 and both of us thought that's the worst thing we've ever heard in our careers. She's a mother, a beloved mother and a beloved daughter and she didn't deserve that and I was utterly disgusted by that." Salisbury Poisonings: The Untold Story - Wednesday April 29, 9pm Channel 4
