Paul Danan is believed to have slipped and fallen at the luxury apartment near Bristol where he was staying.
In a heartbreaking update, the accident is thought to have happened while the actor was full of hopes for a TV comeback after getting life back on track.
The 46-year-old had been put forward to go on Celebs Go Dating and was feeling optimistic after getting his life back on track.
Neighbours told how an ambulance was called to the flat near Bristol on Wednesday evening – but paramedics could not save the star.
Paul, who appeared on Love Island and Celebrity Big Brother, was due to appear in court the following day charged with possession of Class A drugs.
In a podcast seven months ago Paul told how he was living in a ‘dry house’ in Bristol, believed to be the £392,000 flat where he was found dead.
Danan’s neighbours said he ‘kept himself to himself’ in his first-floor apartment.
One said: ‘I didn’t know he was famous, I don’t think anyone living here knew who he was until he died. His family has been here since and asked us not to say anything.’
Another neighbour said she saw an ambulance at the communal entrance to the gated mansion house in Bristol.
She added: ‘I then found out that the man living [in the flat] has died. I didn’t know him, it’s very sad.’
