To Catch a King: The final episode – coming soon…

A grieving father is convinced the police investigation into Lockerbie got it wrong. Myles Bonnar speaks with Jim Swire, whose daughter Flora died in the explosion. He tells Myles he believes the real culprit is Iran. Jim has always been outspoken about his theories. He claims his rising profile attracted unwanted attention from intelligence agencies, both in Britain and abroad. But what did they want with him? Jim tells Myles about David BenAryeah – a supporter of the Lockerbie group who Jim believed was a member of Israeli intelligence agency, Mossad. But Myles knows him as someone very different. Jim Swire’s not the only one who has doubts about who bombed the plane and why. The Lockerbie case has long been at the centre of a complex web of conspiracy. Myles speaks with a member of Abdelbaset al-Megrahi’s appeal team who tell him what they believe really happened in the months leading up to the Pan Am explosion.Lockerbie is produced by Caitlin Smith Additional production by Rob Wilson Sound design by Eloise Whitmore Story consultants are Innes Bowen, Jack Kibble White and Graham Russell Fact checking by Faisal Qureshi Research by Rachael O’Neill and Callum McCulloch-Nowlan Original development by Sally Greig Lockwood Executive Producer: Gillian Wheelan BBC Scotland commissioners: Heather Kane Darling and Victoria Easton-Riley For BBC Radio 4, the commissioning executive is Tracy Williams, and commissioning editor is Dan Clarke.

Myles Bonnar pieces together the original police investigation. He goes back to the night of the explosion; tracking down three sources, each with unique insight into how the police investigation unfolded. From the very early days it’s clear confusion and conspiracy are taking hold. Rumours circulate. Why are American special agents on board the flight? Was the plane used to smuggle drugs? Who are those mysterious figures in the woods in Lockerbie? The police investigation narrows in on a Palestinian militant group. But are they the real culprits?

The search for a convicted people smuggler who put money in the UK planning for retirement.This investigation stems from a tip-off: a convicted smuggler once dubbed the most successful in history, is currently living in the UK and running a string of businesses here. Could it be true?Sue and Rob go on the hunt for Twana Jamal – a smuggler who had so many aliases he had to write them on his baseball cap to remind himself which he was using. In court, prosecutors said he and his gang were making £4 million a year and they believed he was funnelling his money into UK businesses: car washes and mini-markets.The search for Twana Jamal starts in the north of England, where migrants report seeing Twana driving a BMW and exuding an air of wealth. They remember how feared he was in the Calais camp: it was migrants there who reported him to police. His gang was the first to industrialise the lorry crossings, which featured so heavily in 2016 as thousands waited to reach Britain. After a smuggling conviction and five-year prison sentence in France, Twana Jamal entered the UK and is believed to have given a different alias to the Home Office. Sue and Rob track him down to an English village, where he’s running a string of stores selling vapes, sweets and alcohol. Over several days they watch his movements to find out more about his life here. When the moment is right, they plan to confront him.The series is researched and recorded by Sue Mitchell and Rob Lawrie. It is produced and overseen by Joel Moors. Original music is by Mom Tudie. Sound design and mix is by Tom Brignell. Editorial, legal, production and commissioning decisions are overseen by Tracy Williams, Dan Clarke, Joe Kent, Will Drysdale, Lynne Jones and Ross Allen.
