Security has been beefed up at the world famous monument Taj Mahal following reports of a threat from a Pakistan-based terror outfit.

"There is an intelligence report of a terrorist's presence in Agra," Senior Police Superintendent Hari Ram Sharma told UNI in Agra.

Therefore, security has been tightened around Taj Mahal, which attracts a large number of tourists, he added.

Intelligence agencies from time to time issue specific directives regarding terrorists' activities and the present threat perception is one such case, Sharma said.

A few days back, a CD circulated by terror outfit Al Qaeda, indicating threat to Taj Mahal, had caused panic among the security agencies. At least three terrorists have been nabbed in Agra since 2001.
