The car at the centre of the investigation into missing teenager Pheobe Bishop, 17, has reportedly been spotted with black electrical tape on the number plate, obscuring the vehicle’s registration.

The vehicle, a grey Hyundai ix35 with Queensland registration 414 EW3, has been spotted on the streets of Bundaberg in undated photos published by the Courier Mail, with the tape changing the appearance of the registration to 474 BW8.

In addition to the change, the number plate apparently had NSW written on it. On the car, the Hyundai logo had also been crudely transformed into a Toyota logo.

The vehicle is owned by Bishop’s housemate, Tanika Bromley. Bishop lived with Bromley and Bromley’s boyfriend, James Wood, at a derelict property in Gin Gin, about 50km west of Bundaberg.

The vehicle was previously seized by Queensland investigators following the disappearance of Bishop. The teen was last seen travelling to Bundaberg Regional Airport.

Bishop was last seen at about 8.30am on May 15 at Airport Dr in Bundaberg, Queensland. The teenager was planning to fly to Perth to spend time with a boyfriend.

7NEWS is not suggesting Bromley or boyfriend James Wood are involved in the disappearance of Bishop. Police have repeatedly said both parties have been co-operative in the investigation.

However, the mystery continues to deepen following the teenager’s disappearance.

Detective Acting Inspector Ryan Thompson told media on Tuesday, the vehicle had been seized and released by police.

“The vehicle was seized by police and treated as a crime scene. A number of examinations were conducted on that vehicle and items seized and that has since been released by police,” he said.

After being asked about the altered number plates, he said: “Police are aware of the that. We are following up an investigation in relation to that.”

Police have spoken about concerns that pieces of evidence have been moved from the current search area of Good Night Scrub National Park near Gin Gin.

Firefighters, SES crews and specialist police, including police divers, have been searching remote areas near Good Night, deploying drones to scan dense scrub and creek beds.

Bishop’s family has issued a desperate plea for information that could lead to her return, saying it’s unlike the teen to go without contacting anyone for days.

“We need her home,” they said.
