The man was arrested at Sydney Airport yesterday on his return from the Philippines and has been charged with 17 offences relating to two teenage boys who police allege were in his care between 1980 and 1983.

Police said the arrest followed a six-year investigation into allegations of abuse of children at a home in Lismore and other locations in the Mullumbimby area in the early 1980s.

Detective Chief Inspector Cameron Lindsay from Richmond Police District appealed for other alleged victims to contact them.

"We are now appealing for any other victims to come forward that may have been engaged by this man particularly through the use of CB radios and electronic equipment during the late 1970s and early 80s," he said.

"We will allege that this man undertook fixing and playing with radios and electronic equipment within the Mullumbimby area and would entice boys to come and undertake that activity.

"We believe that there will be more victims who will come forward now."

The arrest of the man follows a lengthy overseas hunt for him in a "fairly difficult" part of the Philippines.

The man was arrested by Strike Force Kruseana detectives with South Sydney police officers and the Australian Federal Police on Saturday.

He was charged at Mascot Police Station for offences including two counts of buggery, two counts of attempted buggery, procuring an act of indecency, assault and indecent assault of a male.

He has since been taken to the Prince of Wales Hospital in Randwick with heart issues and will face a bedside hearing, Detective Chief Inspector Lindsay said.

Detectives are wishing to speak to any former residents who were at the home in the early 1980s.

Despite the length of time after the alleged offences occurred, Detective Chief Inspector Cameron Lindsay said it proved it is never too late to come forward.

"It sends a strong message that even those people now that would do bad things to children, that years and years may go by but the police will eventually take action if they receive the information and complaints to take action with," he said.

Anyone with information should contact Crime Stoppers.
