A far-right extremist in England who attempted to burn down a synagogue on the day commemorating the Holocaust ended up engulfing himself in flames, a video released of the attack shows.

Devon and Cornwall Police announced on Friday that Tristan Morgan, 52, has been locked up in a hospital indefinitely after pleading guilty to arson and two terrorism-related charges in connection with the fire at the Exeter Synagogue on July 21, 2018.

Video released by the temple shows Morgan using a small ax to break a window, then pouring a liquid inside. When he threw a burning paper at the broken window, the 52-year-old was engulfed in a blast of fire that left him with burns.

“The footage, which was played in open court, shows the level of planning, determination, and intent by Morgan, whom the wider evidence clearly showed held abhorrent extreme right-wing, anti-Semitic, and white supremacist views," Superintendent Matt Lawler said in a statement. "It is only by sheer chance that the Synagogue was empty and indeed that Morgan himself sustained only minor burns."

Witnesses told a court the 52-year-old had been laughing after he set the building ablaze, the BBC reported.

A judge gave Morgan an indefinite hospital order, and only a court can consider his potential release.

In addition to his hospital hold, Morgan was handed down a 10-year terrorist notification order, which places him under long-term monitoring by police.
