Sweden’s government said on Wednesday it planned to introduce legislation requiring social media platforms like TikTok and Snapchat to take down criminal gangs’ ‘murder adverts’ within an hour or face hefty fines.

Criminal gangs active in Sweden increasingly use social media to recruit people to commit murders and other violent acts amid a surge in “crime as a service”.

The recruits are often children under the age of 15, Sweden’s age of criminal responsibility, meaning the youngsters cannot be prosecuted and fall under the responsibility of social services, making them valuable assets to the gangs.

“We will be first (in the European Union) with this kind of legislation targeting organised crime’s recruiting of children and youths,” Swedish Justice Minister Gunnar Strömmer told a press conference.

The minority right-wing government, propped up by the far-right Sweden Democrats, has been pushing through a rash of proposals cracking down on crime and immigration in the run-up to Sweden’s general election on September 13.

If the proposal is adopted by parliament, social media sites would as of July 15 face fines of up to five million kronor (US$537,000) if they fail to take down the adverts in time.
