Celebrity Big Brother's Bit On The Side taken off air after row between guests
Celebrity Big Brother spin-off show Bit On The Side had to be taken off air 10 minutes early on Tuesday night after a row between two guests.
Transmission was cut after former contestant Aisleyne Horgan-Wallace appeared to throw champagne at housemate Farrah Abraham.
A Channel 5 spokesman said: "Bit On The Side was interrupted due to an incident on the set."
Actress Vicki Michelle, 64, says she had to have treatment after the show.
Michelle, who played Yvette on 80s comedy series 'Allo 'Allo, tweeted about the incident.
The argument between Horgan-Wallace and Abraham started as they were being interviewed by Bit On The Side's host Rylan Clark with the latest evicted celebrities Jenna Jameson and Janice Dickinson.
Clark, who finished fifth on The X Factor in 2012 and won Celebrity Big Brother 11 the following year, asked 36-year-old Horgan-Wallace: "Do you miss Farrah being in the house?"
"No I don't. She was just horrible," the former Big Brother 7 star replied.
"She never took accountability for anything she did because she's a silly little girl.
"It's just pathetic. She's just nasty. There's one thing standing up for yourself and being a strong woman. There's another thing being... nasty... horrible...
"You've got your cheque, get on your plane... No-one likes you here."
Abraham, who appeared in US reality shows 16 and Pregnant and Teen Mom, hit back by slow-clapping Horgan-Wallace, saying: "Well done. Good job."
Later in the show, the 24-year-old American was asked her opinion of fellow Celebrity Big Brother housemate Austin Armacost.
As she started to talk about his anger issues, Horgan-Wallace could be heard saying it was a shame Abraham didn't work through her own issues.
"Hag, be quiet," said Abraham.
"Sorry?" Horgan-Wallace queried as Clark ordered everyone to "calm down".
The screen then flashed to the UK vs USA logo before Clark returned saying: "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."
The show ended 10 minutes earlier than scheduled with users on Twitter posting that a fight had started between Abraham and Horgan-Wallace which left Michelle injured.
Rylan Clark tweeted his apologies to viewers.
Hertfordshire Police sent Newsbeat a statement.
"Hertfordshire Constabulary received a report at 10.55pm on the evening of Tuesday, September 22nd regarding an incident which is alleged to have occurred in the Elstree Studios in Borehamwood.
"The incident occurred a short time before the call.
"Officers are currently making inquiries to establish the exact circumstances of what happened and will release further details when appropriate."
Media watchdog Ofcom says it's had three complaints about the show and will assess any more it receives before deciding whether to investigate.
