Police have searched the property of a man arrested in relation to the disappearance of a Pemberton father three days ago. Homicide detectives have confirmed they are treating the disappearance Tony Ditri — who was last seen leaving Pemberton on Friday afternoon — as suspicious. The 40-year-old left his Guppy Street home to go to the local tip but concerns were raised when he failed to show up for dinner that night, with his car later found in bushland about 20km from the town site. A man in his 60s has been in custody since Saturday and is assisting police with their enquires. The West Australian understands the man in custody and Mr Ditri were known to each other. The roads leading to his property have been blocked off by police, who are understood to be searching the area. It is understood Mr Ditri’s white Isuzu truck was dumped in the bush nearby. The West Australian understands the homicide squad launched an investigation into Mr Ditri’s disappearance the following day, after receiving intelligence from local sources about the suspicious disappearance. A massive search was launched by State Emergency Service volunteers and hundreds of Pemberton residents, combing through the area for any sign of Mr Ditri, however it is understood that search has now been suspended. Detectives are continuing with their enquires and charges are yet to be laid. Manjimup Shire president Paul Omodei said the community was reeling from shock. “Tony is a very well known, loved and respected family man,” he told The West Australian. “Our thoughts are with his family and loved ones. “I just encourage everyone to stick together and look out for one another.” One of Mr Ditri’s friends said it was “surreal” to be searching the bush “for a sign or clue that can point us in the direction” of the well-loved missing man. “Extremely unusual circumstances — Tony is one of the most genuine humans you will ever meet,” he said. “Someone knows something and if you do please report it to the police.” Police are anyone who has seen Mr Ditri or has information regarding his whereabouts to contact police on 131 444 or Crime Stoppers on 1800 333 000.
