Europol has announced the arrests of 66 people following a four-year investigation into an organized-crime group accused of selling horse meat "not suitable for consumption" as beef products. The investigation began in 2013 after Irish authorities found products sold as beef burgers that contained horse meat and led to a Dutch man in Spain alleged to be the leader of the scheme. According to Europol's July 16, 2017, press release, "Investigators concluded that the Spanish element of this organisation was a small part of the whole European structure controlled by the Dutch suspect."
