The comedian attended a police station in south London on Thursday. The Met Police confirmed a man in his forties was in attendance and the individual was interviewed under caution, reports the Mirror.
It comes as the 48-year-old was previously accused of rape, sexual assault and emotional abuse at the peak of his fame - all of which he has denied.
A spokesperson for The Met Police told the Mirror: "A man in his 40s attended a police station in South London on Thursday 16 November 2023. He was interviewed under caution by detectives in relation to three non-recent sexual offences. Enquiries continue."
In September, Channel 4's Dispatches, The Times and The Sunday Times published allegations after four women came forward with claims of incidents taking place between 2006 and 2013 at the height of Brand's career.
However, it's unclear whether his questioning by the police is in relation to the allegations made in the documentary.
Detective Superintendent Andy Furphy who is heading the inquiry previously said: "We continue to encourage anyone who believes they may have been a victim of a sexual offence, no matter how long ago it was, to contact us.
"We understand it can feel like a difficult step to take, and I want to reassure that we have a team of specialist officers available to advise and support."
Following recent allegations, Russell issued a statement, which included his denial.
He wrote: "What I seriously refute are these very, very serious criminal allegations. Also, it's worth mentioning that there are witnesses whose evidence directly contradicts the narrative that these two mainstream media outlets are trying to construct, apparently, in what seems to me to be a coordinated attack.
"Now, I don't wanna get into this any further because of the serious nature of the allegations, but I feel like I'm being attacked and plainly they're working very closely together. We are obviously going to look into this matter 'cause it's very, very serious."
