The activist who tied himself to a goal post at Goodison Park was sentenced to six weeks in prison.
Louis McKechnie used a mentally forced zipper to tie himself up by the neck during Everton’s clash with Newcastle United in March, leading to a lengthy stoppage and his eventual sending off and arrest.
Wearing an orange Just Stop Oil t-shirt, the protester was part of a civil resistance group that wanted the government to act to end the use of fossil fuels.
During his trial at South Sefton Magistrates’ Court, the 21-year-old denied aggravated trespassing, but was found guilty on Friday and was also fined £50, or given a day’s detention , for going to the field of play, subject to a three-year football banning order and ordered to pay £500 in prosecution costs.
PC Colin White, who stopped McKechnie, said: “At this point in the football season Everton were struggling, there was already a lot of frustration in the crowd.
“When Mr. McKechnie came onto the pitch and tied himself to the goal post, there was a lot of frustration, there was a lot of shouting, a lot of abuse and the occasional missile was launched down the pitch towards the aim.”
Although he was given a six-week prison sentence, the court heard that McKechnie, who gave his address as HMP Altcourse, had already served that sentence, having been in custody since July.
However, despite the punishment, the activist said it was “worth it” if his protest saves lives.
McKechnie said: “We came up with the idea of how to get the most attention on that name, Just Stop Oil, and of course football is the biggest cultural phenomenon there is these days.”
He added: “Hopefully public awareness will lead to public action that could actually, if we can get the government to listen to us, could actually save many lives.
“If it’s a chance to save a billion lives, it’s worth it no matter the odds.”
