Home Minister Rajnath Singh on Sunday instructed top police officers across the country not to harass or arrest people on the basis of allegations of radicalisation unless and until concrete proof was available.
Singh also said that genuine NGOs are free to carry out development works but warned that those organisations which allegedly indulge in anti-national activities will not be spared.
This was conveyed by Singh at the concluding day of the three-day conference of DGPs and IGPs here.
The Home Minister told the top police brass categorically that no innocent should be arrested or harassed merely on the allegation of radicalisation and one should be nabbed only after getting adequate proof against the accused, official sources said.
Home Minister, however, directed the DGPs and IGPs to remain alert against attempt to radicalise youths through online and strengthen cyber security apparatus of states.
On Friday, Singh had said that due to close coordination between state and Central forces, Indian youths, who were influenced by the dreaded terror group ISIS through online radicalisation, have not been able to successful to carry out any terror attack in the country yet.
"So far, 67 youths, who were influenced by the ISIS, were arrested while planning to carry out terror attack," he had said.
On Sunday's meeting, the Home Minister also raised the issue of crack down on NGOs saying that no bonafide NGO doing public service will have to face any kind of government scrutiny.
But those NGOs which are allegedly trying to hamper development works or indugle in anti-national activities would not be spared.
Government recently had banned an NGO run by controversial Islamic preacher Zakir Naik for alleged terror acts.
Besides, FCRA registration of around 20,000 NGOs were also cancelled in last two years for various alleged irregularities.
