UK-based prank channel Trollstation have become internet infamous for their totally ridiculous prank videos.
In the past, subscribers have seen them bottle a woman at an anti-domestic violence rally and even stage a hoax suicide bomb alert, but it looks like their latest move was finally one step too far.
Joining the first member of Trollstation who landed himself a prison sentence earlier this year, the other four guys involved with the pranks have now also been sent to actual jail, after staging fake robberies and kidnappings for their YouTube vids.
The fake robbery prank that's landed them all in prison took place in July 2015, when four members of Trollstation swarmed into the National Portrait Gallery to seemingly steal artwork from the walls whilst screaming at other visitors.
Yep, they actually did that. A second prank to seal their prison sentences involved a fake kidnapping at London's Tate Britain.
The four members of Trollstation, aged between 20 and 29, all pleaded guilty to two counts of using threatening and abusive language/behaviour with the intent to cause terror and provoke unlawful violence based on their part with the fake robberies and kidnappings.
For the Tate Britain robbery prank, each member will be jailed for eight weeks, while the little stunt at the National Portrait Gallery will put them behind bars for an additional16-20 weeks each.
Speaking about the verdict, Robert Short of the Crown Prosecution Service said: "The hoaxes may have seemed harmless to them, but they caused genuine distress to a number of members of the public, who should be able to go about their daily business without being put in fear in this way.
"We hope these convictions send a strong message that unlawful activities such as these will not be tolerated in London."
