Former Australian Idol judge and Sony Music executive, Jay Dee Springbett, was found dead at his apartment in eastern Sydney on Thursday.

Springbett, 36, was found unconscious in his apartment at about 3.30 p.m. on Thursday.

When Springbett failed to answer his phone 'concerned associates' called emergency services to check on him. Officers visited Springbett's apartment in New South Wales where they found him unconscious after paramedics responded to reports of a cardiac arrest, an NSW Police spokeswoman told local media on Friday.

An NSW Police spokesman said the death was not suspicious.

Denis Handlin CEO of Sony Music Entertainment said that they became concerned when Springbett failed to answer his phone.

We thought we better let the police know because it's really not like him and then of course they went to his residence and found him, Handlin told 2GB radio.

It's just so difficult coming to terms with it.

Handlin in a statement said that Springbett came to Australia from the UK in 2004 to work in artist and repertoire (A&R) at Sony Music.

Jay Dee was a great friend and larger than life charismatic character who will be missed enormously, the statement said.

Andrew Gunsberg, a former Idol host, tweeted: I'm completely sidelined by the news of Jay Dee Springbett's death. My deepest thoughts are with his family, friends and colleagues.

English-born Springbett was a Sony Music talent scout who replaced shock jock Kyle Sandilands as a judge on the Channel 10 reality show in 2009, ABC news reported.
