[3] According to Roberts, he was mandated to surrender his passport whenever an English football team played abroad following a 2001 conviction for streaking (including FA Cup Final 2001).

[8] On 21 May 2003, in the 2003 UEFA Cup Final at the Estadio Olímpico de Sevilla, Spain, before the start of the match between Celtic Scotland and Porto Portugal, he ran into the center of the field disguised as a referee, presented the referee with a red card, then completely undressed, revealing the words "GoldenPalaceCasino.com Click here" on his back (as part of an advertising deal)[9] while in this state for a few seconds, he picked up the ball and made a slalom pass to the gate protected by Vítor Baía.

In 2007, Roberts ran out on the field of Wembley Stadium during the National Football League's first regular season game outside of North America between the Miami Dolphins and New York Giants.

[15] In 2011, artist Benedikt Dichgans hired Roberts to streak at the Turner Prize awarding ceremony at Tate Britain, but he was tackled by police while only partially on stage, and was arrested.

[18] In 2018, Roberts made his first appearance since 2013 at the Gangneung Oval during the speed skating events of the 2018 Winter Olympics in Pyeongchang, South Korea.

As the men's 1,000-meter speed skating medal ceremony concluded, Roberts took to the ice wearing nothing but a pink tutu and skimpy underwear with the words "peace and love" emblazoned across his bare chest.
