Green campaigner Andy Pag remains trapped in India after his trial for being a suspected terrorist was delayed for a fourth week.

The 35-year-old was arrested for bringing a satellite phone into the country during an attempt to drive around the world in a vegetable oil powered bus.

Complex Indian anti-terror laws require satellite phone owners to obtain a permit, although Mr Pag’s lawyer Prateek Kasliwal claims there is no Government department which issues the permits.

Mr Pag shared a cell with a murderer in the notoriously harsh Amjar prison for four days and spent another three languishing in police custody, but has since been released on bail.

He was the first ever person in the country to be charged for possession of a satellite phone following a night time raid on his eco-bus by armed police officers.

The Thornton Heath resident, who used to live in Wimbledon, faces up to 10 years in prison if convicted on terror charges.

Police in Rajahstan cited a busy schedule policing local elections for failing to submit charges to the court for the fourth week in a row.

More elections are due next week, raising the possibility charges will not be brought on Mr Pag’s next appearance on February 17.

Such a situation would raise further problems for the green campaigner, whose non-renewable tourist visa expires five days later.

Mr Pag said: “I’m certainly not a threat to India’s national security and I think the police realised that very quickly last month.

“I only brought the sat phone because I was worried about kidnappings by terrorists in Pakistan. I haven’t used it at all in India.”

Every time he is due in court, Mr Pag makes a 400km round trip from Jodhpur where he is staying to the court in Ajmer.

He has been charged section 70 of the Information Technology Act, section 4/20 of the Telegraph Act and section 3/6 of the Wireless Act. All carry custodial sentences, the minimum of which is two years.
