Other victims could come forward
THE lead investigator said he believed there may be more of David Merrett's victims who have not come forward yet.
Detective Constable Rick Milburn said several of the incidents dealt with in the past by police have stemmed from his window cleaning business.
"I think there are people out there who are having their windows cleaned to save any problems," he said.
"We know he has a round, but we do not have good enough justification to obtain a court order for his list. But, I would not be surprised if there are other victims who haven't come forward.

"It is possible he is using his aggressive behaviour to get people to use his service.
"I can understand why people don't want to intimidate him, but if anyone wants to report him or their concerns about him they can do so."
DC Milburn described the attack on Mr Drummond as "sustained and aggressive".
