In May 2016, four other members of Trollstation were jailed for between 16 and 20 weeks after staging a 'terrifying' fake art heist which caused a stampede at the National Portrait Gallery. Five members of "Trollstation" - some with tights on their heads - burst into the central London art gallery playing a loud alarm and pretended to steal paintings, just a week after the 2015 Sousse attacks. The gallery's visitors fled in apparent panic and one woman passed out, while others were trampled on in the rush before the group moved on to Tate Britain where they carried out a fake robbery and kidnapping, a court was told.
