Spanish authorities said Friday they had shut down the country’s biggest illegal streaming platform Cristal Azul, which had been offering La Liga and second division football matches online for free.

“More than 78,000 community members… were benefiting from the broadcasting, defrauding two well-known Spanish companies of more than €42 million ($44.4 million),” said Spain’s Guardia Civil, a national law enforcement agency, in a statement.

The operation began following a complaint filed jointly by La Liga and broadcaster Movistar, and finished with the identification of the alleged perpetrator, a 37-year-old man, now under investigation.
