Keith Flint's Prodigy bandmates were so concerned about his safety that they hired a full-time security guard to keep an eye on him.
According to the Sun, Flint was tailed 24/7 by a minder and said he'd been put on "health watch" after anti-hunt protesters stormed his English pub.
A source said: "Keith's pub, The Leather Bottle, became a meeting place for the local hunt, and this information got out online. A couple of times, anti-hunt protesters turned up and made a fuss. It really upset Keith and I know the band and the management were a bit worried for him.
"He had a local minder, a big Essex lad, who would go everywhere with him.
"Keith told me he'd also been put on 'health watch' by the band. He hinted they were concerned for his health and wanted someone around to keep an eye on him."
The Prodigy have yet to comment on the claims.
Flint was discovered "unresponsive" in his home on Tuesday after police and emergency services were called to the property.
The Prodigy's co-founder Liam Howlett said Flint had "taken his own life".
He wrote on social media: "The news is true. I can't believe I am saying this but our brother Keith took his own life over the weekend.
"I'm shell shocked, f****** angry, confused and heart broken r.i.p brother."
