Police say they have smashed "a criminal group" involved with the unauthorized distribution of video online. Three men in their twenties and thirties have been arrested by Polish police and up to three sites are reported down. The action follows the shutdown of several 'pirate' sites in Poland last month and the arrest of a millionaire businessman.

With web-blockades, domain seizures and payment processor interventions making headlines, campaigns to shut down individual sites have been less prominent than usual in the first half of 2015. But that doesn’t mean they’ve stopped.

Just last week the popular BT-Chat was shut down in Canada following pressure from the MPAA and news from Europe suggests that at least two more sites have fallen in recent days following industry action.

After a long investigation, police in Poland report that authorities swooped last week on individuals said to be part of a “criminal group” involved with the unauthorized distribution of video online, movies in particular. In an operation carried out by municipal police and officers from a regional cybercrime unit, several locations were searched including homes, offices and cars.

Three men aged between 24 and 33 years-old were arrested in Wroclaw, the largest city in western Poland. According to police, 14 computers, 13 external drives, 40 prepaid cards, several mobile phones and sundry other items were seized during the raids.

In addition to the images below, police have put together a video (mp4) of one of the targeted locations complete with a horror movie-style audio track for added impact.

While police have not published the names of the domains allegedly operated by the men, two leading sites have disappeared in recent days without explanation. TNTTorrent.info and Seansik.tv were the country’s 160th and 130th most popular sites overall but neither is currently operational.

The men are being blamed for industry losses of at least $1.3m and together stand accused of breaching copyright law which can carry a jail sentence of up to five years in criminal cases. For reasons that are not entirely clear, however, police are currently advising a potential three year sentence.

The latest shutdowns, which also encompass torrent site Torrent.pl, follow police action in May which closed down eKino.tv and the lesser known Litv.info, Scs.pl and Zalukaj.to. With around 324,000 likes on its Facebook page eKino.tv was by far the most popular site but it seems unlikely that it will return anytime soon. Currently displaying “THE END” on its front page, its owner was arrested last month.

Local media is connecting the closure to the arrest of a 49-year-old businessman who had been running a company offering “Internet services” and also Poland’s largest pirate site. According to authorities he made millions of dollars from the operation and laundered money by investing in the stock exchange. Those funds have reportedly been frozen.

Also arrested were three accomplices, including a 36-year-old allegedly responsible for creating the database of movies and setting up a US company to assist with the site’s finances. They all stand accused of copyright infringement and money laundering offenses and face ten years in prison.
