Chennai : The Tamil Nadu Police is on high alert after inputs from central intelligence agencies on the presence of some Islamic outfits in the state. After the ban on the Popular Front of India (PFI), some human rights groups were conducting programmes on human rights and police action, and central agencies have warned that such outfits were actually fronts of former PFI cadres who were trying to regroup. Sources in the Tamil Nadu Police told IANS that these groups were trying to influence educated youths in campuses who are wedded to Islamic ideology. While many are shying away due to the ban inflicted on the PFI, some youths are being targeted by these groups. The central agencies have warned the state police that some sleeper cells were working in Tamil Nadu supporting the activities of these ‘on paper’ organisations. Even as these groups are focusing on human rights and against “police atrocities”, agencies say that they were trying to create a dedicated support base from among the former PFI activists for further action in Tamil Nadu.
