The man who bought an island, hired hitmen and throttled a theatregoer

Malcolm Potier's dark past was unknown to the woman he strangled at the theatre Theatre-lover Kirsty O'Donnell was a regular visitor to the West End to enjoy musicals and plays. But her life took a dramatic and frightening turn during a performance of Queen musical We Will Rock You at the London Coliseum. She was throttled – a disgraced ex-millionaire who had twice tried to have his former partner murdered. Malcolm Potier launched his violent attack on 51-year-old O'Donnell as she was singing along to Queen hits on . Potier, 75, from Sarratt in Hertfordshire, was found guilty of non-fatal strangulation at Southwark Crown Court in July and jailed for two years on Thursday. The bizarre violent attack was the latest carried out by Potier, once a wealthy landowner who had outbid Sir Mick Jagger to buy a remote Scottish island. O'Donnell was sitting in the dress circle at the London Coliseum when she was attacked Among the crowd at the West End's biggest theatre on the night of the attack were Sir Rod Stewart, former Strictly Come Dancing judge Bruno Tonioli and comedian Jimmy Carr. It was the show's press night, and Potier was sitting next to his partner, theatre critic Lizzie Loveridge, in the dress circle. In her subsequent review, having already taken aim at the production itself, Loveridge wrote: "The other problem at the Coliseum is the behaviour of the audience. "Maybe worst of all are those sing along audience members who inflict their mediocre singing voice on the rest of us." What Loveridge's review failed to mention was that one of those people singing, O'Donnell, was throttled BST. Loveridge had told her to "shut up", to which she replied: "That's a bit rude." Potier then told O'Donnell, "I'll show you what rude is" and pressed down on her neck for up to five seconds. Sir Brian May delivered a guest performance on the night on "This has been particularly difficult because theatres, concerts and public events have always been an important part of my life," O'Donnell told the court. Any trouble confronting what had happened to her was worsened . O'Donnell was told the man she was to give evidence against had twice been jailed for trying to hire a hitman to kill his ex-partner, as well as her significant other. "Because I chose to give evidence, I cannot know whether there may one day be consequences for doing so," she told the judge.
