The family and friends of missing man Sean Mitchell (below) say Aussie police have been unhelpful in the search for the 38-year-old Perth businessman.
Mitchell vanished from a pub in Mosman Park about a week ago, but an official search for him wasn't launched until a diver found some of his belongings several days later at the bottom of Swan River.
Because of a delayed police search, all that's presently known is that Sean Mitchell vanished shortly after attending a work-related party last Friday night at the Belgian Beer Cafe.
He had informed at least one friend by phone as he was leaving that evening that he intended to "sleep overnight on a yacht" belonging to one of his drinking mates.
Mitchell abruptly disappeared shortly thereafter, but, almost five days in, police still hadn't "seriously" responded to his missing persons report.
"I am obviously scared that he did not get on the yacht," a female colleague Mitchell spoke to by phone on the Friday he went missing told reporters this week. "It is really frustrating."
The lost Australian was electronically tagged using Perth's rail station around 9:00 p.m. last Friday, and his cell phone pinged one final time near Mosman Park's Freshwater Bay yacht club -- a little more than an hour after this last known sighting.
Missing man Sean Mitchell, who operates a mining-recruiter enterprise, is an adult Caucasian male with red hair, blue eyes, and a "medium build."
Anyone with information about his disappearance in Perth, or with knowledge of Mitchell's current whereabouts, should contact police at 131-444 immediately.
