New image released in hunt for Bung

Victorian police have released an image of a white station wagon possibly related to missing schoolgirl Siriyakorn 'Bung' Siriboon on the third anniversary of her disappearance.

The 13-year-old was last seen by a neighbour on her way to school in Boronia on June 2, 2011.

Detectives say they are looking into a report of a young girl who was seen in the rear passenger seat of a white Ford Falcon wagon on Boronia Road between 8.30am and 9am on the day Bung disappeared.

The female seen in the back of the car was of Asian appearance, in her early to mid teens and wearing a light-coloured collared shirt and blue v-neck jumper.

The driver of the car was a man described as being of Caucasian appearance in his late 50s to early 60s and wearing a blue singlet, light brown hair combed back in "rock and roll" style and a tattoo on his left upper arm.

"The sighting may well be completely innocent, but it is relevant to us and we need to investigate it," Detective Inspector John Potter said.

"It's now been three years since Bung left home and failed to arrive at school that day and has not been seen or heard from since.

"We continue to hold grave fears for her safety and are desperate to provide her with some answers."

The Ford Falcon wagon appeared to be an EA to EF which range from models in 1988 to 1996.

Bung is of Thai origin, about 154cm tall with long dark hair and brown eyes.

A reward of up to $1m for information leading to the arrest and conviction of the person or people involved is on offer.
