Gutter filth! Bowling alley bosses launch investigation after hardcore porn movie is filmed at their venue

The rude revelation has been a particular blow to manager Mr Parsonage, who took over the reins 18 months ago and is currently negotiating to take over the lease.

He has ploughed money and time into making the Pershore Road premises family-friendly - and stresses the filthy footage must be some years old, taken long before they moved in.

'We are currently going through old documents, invoices and CCTV footage, which we still have access to,' he said.

'There must have been some payment,' he added. 'I have my suspicions, but that is all I'm prepared to say. I don't need this - this is a family venue.' 

The film shows the trio indulging in sex on the business's colourful furniture, with PSL's bowling alley in the background

It's not the first time the popular venue has appeared on the small screen, albeit in less sensual circumstances - scenes from popular BBC daytime show doctors were once filmed there.

In January the vicar of a 137-year-old church described the decision by an adult film company to shoot an explicit fetish video on their grounds as 'upsetting'.

Paul Tullet, vicar at Water Orton Parish Church in north Warwickshire, said no permission had been sought by website PornXN to record on its premises after a hardcore video shot at the front door was uploaded online.

The film, featuring Hungarian porn star Lyen Parker, shows the actress exposing her naked body and urinating in public.
