BANGKOK, Sept. 11 -- Thai police has reportedly arrested the chief arm procurer of the Sri Lanka militant group Tamil Tigers, media here reported Tuesday, citing foreign sources.

       Citing a report from online newspaper Asian Tribune from Sri Lanka, Bangkok Post and The Nation news website here said that Kumaran Pathmanadan has been arrested by police in Bangkok on Monday evening, although Thai authorities have not yet confirmed the news.

       Pathmanadan is allegedly one of the top officials in the Liberation Tigers of Tamil Eelam, the formal name of for Tamil Tigers, and the group's chief procurer of arms. He has been on Interpol's Most Wanted list for a number of years, and also been implicated in several assassinations of political leaders.
