Baywatch actor Jeremy Jackson, 34, was removed from the Celebrity Big Brother house on Saturday after opening up the 21-year-old model's robe, exposing her and groping her in the bathroom of the house.
CBB viewers watched as Chloe Goodman exited the bathroom in floods of tears following the incident.
In tears and breathless, Chloe was seen sobbing: “It’s just the shock, it’s just the shock.”
A number of people who were watching the show at the time decided to call the police and report the incident.
Chloe had not made a complaint about Jackson, and the actor was not arrested, but he did accept a formal warning for common assault after voluntarily meeting with Hertfordshire officers.
Herts police spokeswoman told The Mirror: "A 34-year-old man voluntarily attended Hatfield Police station this afternoon to assist police with their enquiries into an incident which is alleged to have taken place in the Big Brother House in Borehamwood in the early hours of Saturday January 10th.
"The man has subsequently been issued with a police caution for common assault."
Jeremy said of his behaviour was wrong: "It was a terrible drunken mistake - I’m so ashamed."
In an unrelated incident, former Coronation Street star Ken Morley has also been removed from the Big Brother house for "unacceptable and offensive language".
