Peter Foster, the conman behind dubious oral weight loss sprays, is on Interpol’s wanted list after failing to front an Australian court.

An Interpol alert has been issued for the arrest of Australian conman Peter Foster.

Australian authorities asked Interpol to list the 51-year-old fugitive under a red notice after Foster failed to front a Federal Court hearing in Brisbane last year.

The Interpol website says Foster is facing a contempt of court charge and anyone with information should contact their national or local police.

An Australian Federal Police spokesman says the Interpol notice means authorities overseas will alert their Australian counterparts if Foster is spotted.

The Australian government will then send over the necessary paperwork for his arrest and extradition to Australia.

In December, Foster failed to appear for a Federal Court hearing.

He had started legal proceedings to appeal a three-year prison term handed to him in his absence in October 2013 for his part in the sale of a bogus SensaSlim oral weight loss spray.

Foster had claimed to be hiding in Fiji but was ordered back to court last year to show why his appeal shouldn’t be thrown out for abuse of process.
