Terrified regulars at the Queenâ€™s Arms have been keeping their backs to the wall since they realised the randy ghost was stalking the bar.
And it has become so bothersome that the exasperated owners have had called in a team of ghostbusters to give the saucy spook the bumâ€™s rush.
Staff at the Birmingham city centre boozer have nicknamed the ghost Grasper after they described feeling a â€œfirm pinchâ€ to the buttocks.
Assistant manager Paula Wharton, 41, initially believed the tweaks on her body were muscle spasms.
She said: â€œOne night three of us were talking and I mentioned that Iâ€™d felt this pinch on my bum, and everyone else said that it had happened to them too.
â€œIt canâ€™t have been a customer as Iâ€™ve never had my bum pinched when Iâ€™ve been stood behind the bar.
â€œItâ€™s happened to all of us on a few occasions, it can happen at any time, night or day.
â€œWeâ€™ve nicknamed the ghoul Grasper after Casper the friendly ghost but heâ€™s a bit too friendly for our liking.â€
But itâ€™s not just staff at the pub who have felt the pinch â€” customers have also fallen victim to the ghoulâ€™s roving hands.
Pretty Ashley Beland, 26, said she thought she had been groped after her encounter with the ghost.
She said: â€œI was stood at the bar enjoying a glass of wine when I suddenly felt a sharp pinch to my bum.
â€œMy instant reaction was that it might have been a sleazy bloke trying his luck, but when I spun around ready to give him a piece of my mind there was no-one there.
â€œI was really confused until the staff explained that there was a ghost running around the place pinching people on the bottom.
â€œIt was a little scary, but I suppose there are worse things that a ghost could do to you.â€
Customers have also witnessed chairs moving on their own, heard footsteps when the pub is empty and seen plumes of smoke swirling around.
And it is even thought that several ghouls may lurk around the 170-year-old pub after last orders.
A bald-headed ghost has been spotted walking through walls to find the bar, while rumours suggest that a young girl died in the building decades ago after falling down the stairs. …
