IT was uncharted territory for Britain, let alone Hampshire police.

The extradition of Kohli from India was the first time ever since a treaty was signed between the two countries in 1993.

Detectives were asked to compile an extradition file so damning that Indian authorities would be convinced he should be sent back to the UK for trial.

They were given a 60-day period to get the document together which needed to include statements from witnesses to show there was evidence Kohli needed to return and face trial.

For Det sgt Steve Mardon it was one of the most stressful parts of the investigation.

He said: "The process involved getting 30 witnesses in front of the court as part of the file, in order to satisfy the Indian courts we had enough evidence.

"It sounds like a long time but it's not. Worked round the clock to ensure even down to spelling was ok. We had to be absolutely correct in every single piece or they would have rejected it. We spent many late nights, checking and double-checking. Everything was new to us You only get one go or that's it, they would have had to let him go."

The files accepted, dozens of court hearings followed before the most senior judiciary in india approved the request and ordered Kohli be sent back to the UK in July 2007.
