Police in Australia have announced a new reward of up to A$500,000 (£240,000; $325,000) for information leading to the discovery of the remains of British backpacker Peter Falconio, 24 years after his murder.

Mr Falconio was shot dead on a remote stretch of highway about 300km (190miles) north of Alice Springs in July 2001.

The 28-year-old from Huddersfield was travelling around Australia with his girlfriend, Joanne Lees, who was also from the West Yorkshire town.

In 2005, Bradley Murdoch was convicted of murdering Mr Falconio, but has never revealed the location of his body.

Murdoch was also convicted of the attempted kidnap and assault of Ms Lees, who managed to escape by hiding in the surrounding bushland.
