The housemate of a missing Bundaberg teenager has been released without charge after being questioned by police.

Queensland Police yesterday took 34-year-old James Wood into custody over the disappearance of 17-year-old Pheobe Bishop three weeks ago.

No charges were laid.

Bishop disappeared three weeks ago.

She lived with Wood and his partner Tanika Bromley in a share home in Gin Gin.

They were the final individuals to witness her before she was dropped off at Bundaberg Airport for her flight to Western Australia with a stopover in Brisbane, around 8:30 am on May 15.

Pheobe was meant to visit her boyfriend in Western Australia but, according to police, never checked in for her flight or entered the terminal.

Police, with the help of the Homicide Investigation Unit, are continuing to investigate Pheobe’s suspicious disappearance.

Recently, police halted their search efforts in the Good Night Scrub National Park, located roughly an hour from where Pheobe was last observed, a location that had been central to their investigation.

They said they found evidence linked to the teen’s disappearance but have not said what they found.

Detectives also said they believe evidence had been moved from the bushland prior to their search. 

Two crime scenes have been declared — the home in Gin Gin and her housemate’s grey Hyundai ix35 with registration 414EW3.

A search of the car led police to allegedly find a shortened firearm, ammunition, and two replica handguns.

More ammunition was allegedly found at a home in Gin Gin. 

Bromley and Wood have since been charged with unrelated weapons offences. 

They remain before the courts on the weapons charges.
