Acting on specific Intelligence, the Q branch sleuths arrested J Thambi Annan alias Daniel (46), hailing from Kilinochchi in Sri Lanka.
Describing the arrest as a ''significant and important catch'', top police officials said Daniel was heading the LTTE's procurement module and has been in the top of the outfit's hierarchy.
