Immunity deal is offered a decade after a 13-year-old teen girl vanished without a trace on her way to school – after $1m reward failed to identify any leads

  • ‘Bung’ Siriboon 13, vanished on her way to school in Melbourne in June 2011  
  • Wednesday marked the 10-year anniversary since the school girl disappeared
  • Police have made a fresh appeal for information, releasing a photo of the teen
  • Prosecutors have offered to grant immunity in exchange for information

Prosecutors have offered to grant immunity in exchange for information identifying the person responsible for the disappearance of missing Melbourne teenager Siriyakorn ‘Bung’ Siriboon.  

Wednesday’s 10-year anniversary of her disappearance was marked by Victoria Police making a fresh public appeal for information as they released a photo of the 13-year-old schoolgirl.

Bung dressed in her uniform and left home about 8.30am on June 2, 2011 to walk to school in Melbourne’s outer east.

The Boronia teen never made it.

Despite a number of public appeals and a reward of up to $1million, the case continues to baffle Victoria Police.

Detective Leading Senior Constable Justin Tippett said their thoughts were with Bung’s family, especially her mother Nid, father Fred and sister.

‘Ten years is a long time to go without answers and I’m sure the loss of Bung feels as raw today as it did in 2011.

‘Despite a significant and thorough investigation, we’ve unfortunately not been able to solve this case and either provide Bung’s family with answers or hold the offender to account.’

Apart from the reward, the Department of Public Prosecutions would also consider giving indemnification from prosecution.

Sen Const Tippett said police continue to receive weekly calls and emails about Bung’s disappearance.

‘As history has shown, often those involved in a crime of this nature are unable to keep it secret, so we are especially keen to hear from anyone who may have specific knowledge of the person involved,’ he said.

Five years ago, police released information about a vehicle similar to a white Kingswood station wagon that was seen in Rowville the morning Bung disappeared.

It may have had a young female passenger, but police have never confirmed whether it was Bung or if there was any connection to her disappearance.

A school backpack she was carrying also is yet to be found.

Anyone with information is urged to call Crimestoppers.

The mysterious case of missing schoolgirl Siriyakorn ‘Bung’ Siriboon

Bung was last seen by a neighbour leaving her Elsie Street home in Boronia and heading towards Albert Avenue shortly after 8.30am in her school uniform on June 2, 2011. 

She was wearing her blue and white school uniform when she disappeared.

Police investigated information Bung was spotted in the rear passenger seat of a white EA to EF model Ford Falcon station wagon on Boronia Road between 8.30am and 9am on June 2.

The female was described as being of Asian appearance, in her early to mid teens and was wearing a light-coloured, collared shirt and a dark blue v-neck jumper.

The man driving the car was Caucasian, in his late 50s or early 60s, wearing a blue singlet, with a tattooed left arm and a ‘rock and roll styled hairdo’.

‘The witness stopped at the traffic lights next to the car and found the scenario ”odd”,’ according to police.

More than 1,000 homes were door-knocked and at least 1,200 leads closely examined as police tried to solve the mystery.

But Taskforce Puma, which was set up four months after her disappearance, was shut down in 2013 as the leads dried up. 

A reward of $1million remains for information leading to the conviction of the person or persons responsible for Bung’s sudden disappearance.
