Svensson also served as the defendant to Lars Tingström ( known in Sweden by the nickname '' Bombmannen '' , " the Bomb-Man " ) , who was later convicted of three bomb attacks around Stockholm . In 1996 Svensson published parts of what he said was a testament authored by Tingström shortly before his death in 1993 . In the purported testament , Tingström wrote that he had given Christer Pettersson the instructions to assassinate Swedish Prime Minister Olof Palme . The journalist Gunnar Wall wrote an article in '' Dagens Nyheter '' where he accused Svensson of manipulating the testament from Tingström . A forensic investigation later proved the testament to be real . Svensson 's information led the prosecutors to file an application for a new trial against Pettersson for the assassination of Palme , but this was rejected by the Supreme Court
