 At Birmingham Crown Court in October 2014 , he pleaded guilty to three charges of possessing a prohibited firearm , to putting a neighbour in fear of violence , and to making an improvised explosive device . He was again ordered to be detained indefinitely , this time under sections 37 and 41 of the Mental Health Act 1983 , by Mr Justice Blair , who said that " The effect of these orders is that the defendant may never be released " . He also likened Williams 's more recent behaviour to that leading up to the 1978 incident and said that " a similar tragedy had been narrowly averted " . Williams was returned to Ashworth Hospital , where he was already being treated on recall from his previous detention .
