Celebrity Big Brother's Bit On The Side forced off air after 'fight breaks out'

Police are investigating a brawl which forced Celebrity Big Brother's Bit On The Side off air last night.

A brawl erupted when ex-contestant Aisleyne Horgan-Wallace branded housemate Farrah Abraham, an American reality TV star, a "horrible b****".

A CBB source said there was "drink throwing and glass throwing and chair throwing", which forced security to rush in to break up the melee.

'Allo 'Allo actress Vicki Michelle was injured by flying glass and taken to hospital.

Michelle later tweeted that she had been "bloody hurt" but was "ok".

Hertfordshire Police confirmed officers were now investigating the incident.

Abraham, Horgan-Wallace and Michelle were panellists on the spin-off show, presented by Rylan Clark.

The war of words began when Clark asked Horgan-Wallace: "Do you miss Farrah being in the house?"

"No I don't. She was just horrible," the former Big Brother 7 star responded. "She never took accountability for anything she did because she's a silly little girl.

The 24-year-old later told Horgan-Wallace: "Hag, be quiet!"

"Sorry?" Horgan-Wallace replied as Clark pleaded for everyone to "calm down".

Clark returned to tell viewers that "we have lost our panel for the evening".

"Hi guys, unfortunately, we did have to pop that up there due to a matter that happened, er, unfortunately we have lost our panel for the evening, but we are going to carry on," he said.

The former X Factor star - who won Celebrity Big Brother when he appeared on the show in 2013 - tweeted an apology to fans, saying transmission was cut for "reasons out of our control".

A Channel 5 spokesman said the show was interrupted due to "an incident on the set", but did not disclose details.

Horgan-Wallace claimed there was "a lot of misconstrued stories" about the incident, promising to "set the record straight" at a later date.
