Police will maintain tight security for the fourth cricket test against Australia following TV news reports of a terrorist threat targeting Sachin Tendulkar.

Nagpur police commissioner Pravin Dixit rejected reports of a new threat to the star Indian batsman, but said authorities worked on the presumption that anything was possible after a threat from militant organizations was received by federal agencies a few years ago.

"There will be tight security as usual, but there´s no new threat," Dixit told The Associated Press. "The center (federal government) had issued an advisory a few years ago, but at present there is no threat.

"Security is always tight."

Indian TV reports said federal intelligence agencies had sent a high alert after intercepting communications mentioning "Sachin."

Tendulkar became the highest run scorer in test cricket history earlier in the series, which India leads 1-0 ahead of the fourth and last match starting Thursday.
