Porn star Pirates fan prompts police probe into masked cop

Police in Pittsburgh have launched a probe into one of its officers after he posed for a picture with a porn star while wearing a unicorn's head.

The incriminating photograph, posted on Twitter, shows the unidentified, rubber-masked officer posing playfully in the lobby of a police station next to laughing adult actress Andy San Dimas.

The cop was caught in the compromising position after San Dimas was thrown out of a Pittsburgh Pirates baseball game and arrested for refusing to sit down while performing a dance in the stands.

The 26-year-old adult film star— who starred in films including Breaking Bad XXX and Shades of Kink — had been kicked out of PNC Park July 13.

Authorities discovered the photo on social media, police spokeswoman Diane Richard said. It shows a muscular man in what appears to be a police uniform standing with Andy San Dimas, a Baltimore porn star who was in Pittsburgh to perform at Cheerleaders in the Strip District that weekend. San Dimas wore a Pirates shirt. The officer cannot be identified because his face his hidden by the unicorn mask.

Acting Pittsburgh Police Chief Regina McDonald said in a statement: 'We are aware of the photos on the Internet (Facebook) and are currently investigating the incident.  

The investigation is understood to to be probing whether the officer's behavior was appropriate under the circumstances.

Before her arrest, San Dimas had posted a string of photographs of her wearing the mask in and around PNC Park.

But during the game San Dimas, who was in town for a performance, stood up and danced, shaking her backside in rhythm with the music, while wearing the mask.

Deadspin reported that when she was asked by an usher to sit down, she replied: "Oh, I'm sorry I was trying to have a good time at the f***ing Pirates game!"

San Dimas' producer Stevie Hughes defended the cop after news of the internal police probe surfaced.

"We don’t want him getting in any trouble because he didn’t do anything wrong," she told ABC's Channel 4 Action News.

"We took (the picture) down because we don't want him to get in any trouble because there's no reason he should be in trouble."

She said they had been wearing the unicorn mask all day, asking other baseball fans to wear it, taking pictures and posting them on Twitter.

Remember. Porn stars, unicorns and cops don't mix.
