Police were called after a mum who took her three sons for a fancy meal at the O2 arena spotted hardcore PORN on the restaurant computer.
Jade Miller, 27, was stunned after her boys spotted the booking computer screen was showing gay website Meatspin.
The explicit clip shows a man engaging in sex with a transsexual with a rotating ‘helicopter’ penis, while Dead or Alive’s classic “You Spin Me Right Round (Like A Record)” is played on a loop.
Mum Jade was with her three boys at Jimmy’s restaurant at The O2 in Greenwich last month when her two eldest told her they had seen “something bad.”
Jade, of New Eltham, south east London, said: “Just as we were leaving the boys said to me ‘there’s something bad on the computer mummy’.
“I went over and had a look and there was gay porn on the screen and some kids were standing there laughing their heads off.
“I don’t think they understood what was going on. Long story short, there was gay porn, two men having sex and my children witnessed all of this.
“I’m in such shock, what do you say to a six-year-old and a nine-year-old when they’ve just seen porn?”
Angry Jade rang police, and insisted staff left the spinning penis, complete with rotation counter, on the screen to use as evidence.
She added: “I feel absolutely sick regarding this matter. It wasn’t dealt with properly.”
The Met Police confirmed they were called to the restaurant at 10.30pm on January 26 after reports of inappropriate material being displayed on a screen in a public area of the restaurant.
A spokesperson added: “Officers believe, at this stage, that the material shown was the result of a pop-up which had been received via the restaurant’s email booking system.
“Officers spoke with the restaurant’s manager and provided advice around computer security and spam management.”
Jimmy’s restaurant refused to comment about the incident.
