Beijing police arrested at least four people for their involvement in a sex tape that was shot at a Uniqlo store, according to a statement released Sunday. The video that blew up on social media was allegedly shot inside of a Uniqlo dressing room in April.

Of those arrested, a 19-year-old man who goes by the surname Sun was charged with distributing the obscene material, the Beijing police statement said. The statement also references three others who were detained, along with the man and woman seen in the video. It was not clear if the couple were included in the tally or were in addition to the three others detained.

According to the police statement the couple said they sent the video to a friend on the WeChat app, the AP reported. The video eventually wound up being shared around on Sina Weibo.

Although Uniqlo denies any involvement in the video, police were also investigating whether or not the video was a publicity stunt carried out by the store.
