New information has been released on the fifth anniversary of the disappearance of Boronia teen Bung Siriboon.

Despite a $1 million reward on offer, police are still no closer to discovering what happened to Siriyakorn Bung Siriboon in 2011.

It’s exactly five years to the day since she went missing.

Then 13, the young teen left her Elsie Street home at Boronia at 8.30am.

Police had initially said there were two possible sightings of her that morning, but it’s since been revealed there was a third.

She was possibly in a white station wagon, which was seen on Napoleon Road near the intersection of Kelletts Road between 8.45am and 9am.

The car, thought to be an early 1970s model Holden HQ Kingswood, was being driven by a caucasian man aged in his 30s or early 40s.

He had a large tattoo on the left side of his neck and sleeve style tattoos on both arms.

Anyone with information should contact Crime Stoppers on 1800 333 000.
