The father of two said he and a friend followed the man in the hope they could find his address and report it to police.

Though they lost the person, who was driving an older-style red Holden, along one of the back streets, the friends said they nevertheless reported the incident to Maitland police.

“I just want people using the toilet facilities at Maitland Park to watch out for this man – and any others like him,” the Maitland father, who asked that his name not be printed, said.

“I was suddenly aware of a man’s face peering through a crack in the toilet door,” the victim said.

“He ducked away and I followed him as quickly as I could.

“Outside the toilet facilities, I saw him climb into an older type, red Holden and drive off.

“My friend was sitting in my car, so we decided to follow him,” he said.

“He knew we were on his tail as we neared Kurri Kurri, so he shot off down the back streets,” the man said.

“We stuck to the speed limit and he was going much faster, so there was no way we were going to catch him.

“But I wanted to tell the Mercury so they could alert other people who use the toilets in Maitland Park.

“I have two young children myself and that sort of behaviour is just not on.”

The man was described as fairly slim, in his 50s with a beard.

Anyone with information should ring Maitland police on 4934 0200.
