Police have been called in over Daley Ojuederie's 'attack' on Hazel O’Sullivan in the Big Brother 2013 house.
Daley was booted out of the house earlier this month following the incident on in the safe house, with Hazel telling Big Brother she felt "terrified" by the boxer after he "flipped".
He had threatened to "nut her one" after grabbing her by the throat when a playfight between the pair turned ugly.
Hazel herself was issued a formal warning over her part, which included slapping Daley's bum and pulling down her boxers.
The Daily Star now reports that Hertfordshire Police are investigating the “serious incident” at the house, and could interview Hazel in the Diary Room, if she's not going to be evicted soon.
The newspaper claims that cops are after unedited footage of the incident, which was cut from the show's live feed as well as the highlights.
A supposed Big Brother source told the newspaper: “This is one incident that won’t go away. Daley may have been removed but the implications of what he did are rumbling on and it could even end in his arrest.
“In the outside world, if a guy did that to a girl, the cops would want statements. It’s no different for Big Brother.”
A spokesperson for Hertfordshire Police told the newspaper: “We are aware that an incident took place in the Big Brother house on July 14 and are working with the production company to investigate the full circumstances of what happened.”
Reps for Daley and Hazel did not comment, but Daley's agent said he had not yet been interview by police.
