Arunachalam Chrishanthakumar alias A C Shanthan, the de-facto leader of the Liberation Tigers of Tamil Eelam in Britain, was arrested on Tuesday for a second time in less than a year in connection with fund-raising and procurement activities for the militant outfit.

51-year-old Shanthan was first arrested in June 2007 under Britain's Terrorism [ Images ] Act before being released on bail in November.

"The 51-year-old man was arrested by the anti-terrorist units of the Metropolitan Police together with Wiltshire Police at Swindon in the Wiltshire Constabulary today at 6 am at a pre-dawn raid," Wiltshire Police said.

He was re-arrested after three more people were detained for questioning on April 29.

Shanthan was allegedly operating with LTTE [ Images ] leader Anton Balasingham and trying to build up the outfit in London [ Images ]. He had accompanied Balasingham for peace talks in Geneva in 2006.

Shanthan will be produced in a court soon. The LTTE is a banned outfit in the UK.

The police have been granted an extra eight days to question the three men already in custody.
