Addressing the media to mark completion of one year in office of Narendra Modi government, the home minister said strict action would be taken anyone involved in such activities.
"This (incidents of waving of Pakistani flags) happened earlier also (during other governments regime) but it would not be tolerated," he said.
On being asked what India was doing to bring underworld don Dawood Ibrahim back to the country from Pakistan, the minister said Interpol had issued red corner notices against him and many others and the process was on to get hold of the anti-India elements living abroad.
"Whether Dawood Ibrahim, Masood Azhar, or Zakiur Rehman Lakhvi, red corner notices have been issued them and India is doing its best to bring them to justice,"the home minister said.
On whether India would give another dossier to Pakistan on the issue, Singh said: "As of now, there is no such proposal but a dossier has already been given to Pakistan in this regard in 2012".
