RTE telly workers were left holding their noses after someone stashed human FAECES in a fan at the back of a fridge.

Workers caught the fetid stench in the new TV building occupied by staff from shows such as The Late Late Show and The Ray D’Arcy Show.

An insider told the Irish Sun: “The smell was horrific, the type that lingers in your nostrils even when you’ve left.”

Despite scrubbing the fridge, the pong remained — and it wasn’t until a cleaner probed further last week that the ­discharge was discovered.

A bit of cardboard daubed with excrement was eventually found in the refrigerator’s fan.

Another source explained: “It was some weeks ago that they first noticed the stink.

“Management asked everyone to clear out any food from a fridge. Yet the bad smell got even worse — with staff even cracking jokes about an ‘RTE Soiler Alert’.

"Keen to get to the bottom of the issue, the cleaners investigated. And it was only when they removed the fridge they located a piece of cardboard smeared with human dung in its fan.”

Last year, the broadcaster was rocked by allegations against bosses from a whistle-blowing Twitter windbag named ‘Secret RTE Producer’.

Al-loo-ding to the latest Montrose mystery, an insider confided: “People have been wondering about the identity of the person who did this, dubbing him or her ‘The Secret Pooducer’.

“Mostly though, everybody is just glad that the awful smell is gone.”

An RTE source admitted last night: “Someone was talking about an odour but it was sorted out pretty quickly.

“Other people working in the same area weren’t even aware of a bad smell.”
