The caution relates to an incident involving 'CBB' housemate Chloe Goodman, which led to his removal from the house.
Chloe was seen fleeing the ‘CBB’ bathroom in tears during Saturday night’s show, after attempting to assist Jeremy, who was vomiting after heavy drinking.
A tearful Chloe told a selection of the housemates: "I was helping him and he went to my dressing gown top and put my boob out."
She later recalled the incident again the diary room, and Jeremy was given an official warning, before being told that bosses had decided to remove him from the show.
Now, a police statement released to MailOnline explains: “A 34-year-old man voluntarily attended Hatfield Police station this afternoon (January 12) 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.”
The current series has been the most controversial yet, and on Monday night, former ‘Corrie’ star Ken Morley was also removed for persistently using “unacceptable and offensive language”.
Perez Hilton became the third celeb to be given an official warning, after bosses deemed his choice of words, during a conversation with Ken, to be “threatening”.
An eviction was due to take place tonight (Tuesday 13 January), however it has now been cancelled due to Ken's removal from the house.
