Twenty-two people died and hundreds were injured when suicide bomber Salman Abedi detonated an explosive device in the foyer at the venue at the end of an Ariana Grande concert on May 22, 2017.Martin and Eve Hibbert, a father and daughter who suffered disabilities from the incident, are now taking legal action against Richard D Hall, per Rolling Stone UK.Hall, who is a conspiracy theorist, has falsely claimed that the Manchester Arena bombing was faked.He told BBC News last year that he had spied on Eve from a vehicle parked outside her home. Hall reportedly stalked Manchester Arena survivors in an attempt to find out if they were lying about their injuries.According to the Guardian, the Hibbert family sought a restraining injunction and damages last Friday (March 31) after Hall promoted the theory that the attack never happened and reportedly admitted to spying on the victims.On Monday (April 3), the Hibberts’ lawyers said: “We can confirm that proceedings were issued in the high court on Friday on behalf of Martin and his daughter Eve.“Those proceedings are for protection from harassment and misuse of private information and include an application for a restraining injunction and damages.
