An air ambulance was called to Ozzy Osbourne’s Grade II listed mansion in Buckinhamshire on the day that he died.
The Thames Valley air ambulance landed in a field close to Welders House on Tuesday morning at around 10.30am.
Paramedics are said to have battled for two hours to save the 76-year-old Crazy Train singer’s life, but it was to no avail.
A spokesperson for the service confirmed to MailOnline: "We can confirm that our helicopter was dispatched to provide advanced critical care at an incident near Chalfont St Giles yesterday."
He rose from a working-class upbringing in Birmingham to become one of the most iconic figures in heavy metal, with a career spanning more than five decades.

In recent years, the former Black Sabbath frontman had faced significant health challenges. He was diagnosed with Parkinson’s disease in 2003, a condition he made public in 2020. He also underwent multiple operations following a fall in 2019 that aggravated an old spinal injury.
Recovery proved slow, and he was later hospitalised with COVID-19 in 2022, which further affected his mobility.
Despite his catalogue of health woes, his death was said to come as a “shock” to his family, especially after he took to the stage at Aston Villa Park only two weeks ago for a stellar farewell performance.
His sister Jean Powell, 85, told The Mirror: “He was frail but it still came as a shock. He still had plans and things he wanted to do. We don’t know the details of his death, it’s still too early. It’s just so sad. I’m just thankful he died in England.”
Osbourne is survived by another sister and a brother, along with wife Sharon and six children, three of whom he shared with Sharon.
Confirming his passing, they issued a statement which read: "It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning. He was with his family and surrounded by love. We ask everyone to respect our family privacy at this time.”
It was signed by Sharon and four of his children, including Kelly, Jack, Aimiee and Elliot.
