The alleged attack came when the top BBC star was filming cooking show Hungry For It in September. An insider claimed that the attacker forced himself on his victim after knocking on her door and barging in on her during production of the show in central London.
A source told the Sun: “It’s terrifying that something like this was able to happen while working on a show.
“The attacker allegedly forced their way into the room she was in after knocking on the door and once inside forced himself on her.
“It’s rocked the entire crew and has made everyone really nervous.
“None of us ever thought something like this would happen when we signed our contracts to work on the show.

“It’s sent shockwaves through the team and many of us will never get over what has happened.
“I know it’s made several of us think more carefully about how protected we are in this line of work.”
All the show’s crew later reportedly received an email about the allegation.
It expressed “deep regret” about a “sexual allegation during production” and warned staff not to say anything publicly.
City of London Police said they were contacted by another force nine days after the alleged attack.
In a statement, they added: “On Sunday 19 September 2021, City of London Police was contacted by another police force, which had received a late report of a rape that took place on Friday 10 September 2021, at an address in Chancery Lane, EC4A.
“The evidence in the case is currently being reviewed and the female victim has been supported by specifically-trained officers.”
A spokesman for the BBC said: “BBC Studios has robust processes in place to ensure that any of our staff or freelancers who may have been the victim of a crime are given all the appropriate support needed and that the matter is handled with the utmost seriousness and care.”
The show will be broadcast on BBC Three which was recently relaunched as a terrestrial TV channel.
