Sydney: A Pakistan-born university student has been arrested on the charges of training at camps run by al-Qaeda linked militant group Lashkar-e-Toiba (LeT).

Police are investigating whether Izhar ul-Haque, the 21-year-old medical student accused of training at camps run by LeT in Pakistan, was part of a Sydney-based terror cell being set up by Frenchman Willie Brigitte, reports said.

Lashkar is the group linked to Brigitte, a Frenchman deported from Australia late last year and currently being held by French authorities who suspect he was trying to set up a terrorist cell in Sydney.

Australian Foreign Minister Alexander Downer told media in a doorstop interview that police were looking at how deep were Haque's connections with Lashkar and Brigitte.

"He probably has some linkages I would imagine, that is for sure. But whether those are within Australia that'll be something obviously the Federal Police will be investigating."

Haque is the first person charged under tightened anti-terrorism laws introduced after the September 11, 2001 strikes on the US. He faces up to 25 years in jail if found guilty. He has been refused bail and remanded to appear in court on May 5.

The medical student, who has been charged under section 102.5 of the criminal code with having received training from a terrorist organisation, is said to have come on an immigrant visa and has since become an Australian citizen.
