53-year-old Vincenzo Mule has pleaded guilty to sexually abusing two young children after luring them to a park in Perth in April 2016.
The holiday care centre did not realise the children were missing until a member of the public discovered them abandoned in the park and called the police.
Mule had initially pleaded innocent, but in May 2016 damning CCTV footage was released which shows the man being followed by the children.
Mule is being held in custody awaiting sentencing.
