Former X-Factor contestant Mitchell David Callaway has been charged with murdering a baby girl in central western NSW after an investigation spanning almost five years.
The charges come after a nine-month-old girl was found unresponsive in a home at Binnaway, south of Coonabarabran, on July 23, 2018.
Paramedics took the baby to Coonabarabran Hospital where she died a short time later.
Detectives have been investigating the death under Strike Force King.
A warrant was executed at a Binnaway home last month and 37-year-old Callaway was arrested at a home in Bowraville, on the mid north coast hinterland, on Thursday and charged with murder.
He appeared at Macksville Local Court, where he did not apply for bail and it was formally refused.
The former country singer competed in series three of The X-Factor Australia in 2011, placing seventh.
He will next appear before Coffs Harbour Local Court on Tuesday.
