Alberto Del Rio has claimed that he knows the person responsible for leaking nude photos and a sex tape featuring a threesome involving his fiancé Paige. The former WWE star has promised to expose "the m**********r" behind the sex tape leak.

In footage uploaded to video-streaming site Periscope, Alberto, who currently wrestles under the ring name Albert El Patron at TNA, said, "I know it was you."

Without naming anyone in particular, Alberto vowed to reveal the person behind the hack and leak of explicit photos and a video of the former WWE Divas champion.

"I know you did this to me, to my baby," Alberto, who left the entertainment company in September 2016, said in the video.

"But I'm gonna prove that it was you, you piece of s**t. You know she is better than all of you."

Right after the sex tape leak, Paige, whose real name is Saraya-Jade Bevis, confirmed that they were stolen and shared without her consent. "Personal and private photos of mine were stolen and unfortunately they were shared publicly without my consent," she said.

The British female wrestling star recently revealed that following the leak she considered physically harming herself.

"I made a big mistake. Huge. I put trust in the hands of someone that took advantage of a young girl years ago. It was my mistake and I'll always take responsibility," she said on Twitter.

In the same clip, Alberto also took a dig at his former employer WWE. His fiancée, who is on the payroll of the company but serving a suspension since August 2016 for violating a wellness policy, tried to stop him from slamming the federation but without any success.

Alberto's outburst came after Paige pointed out to him that he used adult language and asked if the video was not rated PG.

"Oh no, you work for that company that is PG. I don't work for that f*****g company anymore. Thank god," he said.
