"The man was located and taken to hospital for treatment, where he sadly later died. His death is being treated as non-suspicious and will be referred to the coroner."
Brother and sister were close and Max even made an appearance on Geri's 2010 Life Stories episode with Piers Morgan.
At the time, Max explained how the singer was a 'daddy's girl' and how the pair were left devastated by the death of their father, Laurence, from a heart attack in 1993.

He said during the film: "Young Geri was always wanting to be the centre of attention.
"I think Geri doted heavily on her father. Maybe because of the attention that my father gave her as regards to her potential.
"He obviously saw something early on, so I'd call her a bit of a daddy's girl, definitely."
Police told the newspaper Max, who worked for a green technology company, had been taken to Watford General Hospital by ambulance when he was discovered at home last Wednesday.
