The report said that "the pamphlets featured the name of the al Qaeda leader Ayman al-Zawahiri, who had last month announced the formation of the terror outfit's branch in the Indian subcontinent, wading into a region ripe with fierce anti-western ideology and full of young unemployed men ready to take up guns and fight."
"In the pamphlets, we found words and phrases like ‘mujahid' and ‘salaam to our brothers in Chechnya'. We also found the name of Zawahiri in some pamphlets," a police officer was quoted as saying.
However, the state Home Secretary Basudeb Banerje denied any link with the terror outfit, while addressing the media and said, "Certain media reports said that posters relating to al Qaeda were found. No such posters have been found so far. Investigation is on."
