Megastar Amitabh Bachchan has urged people to act as policemen and suggested initiating an anti-terror training programme that would help them to fight terrorism and protect themselves.

The actor said he would be the first one to join the anti-terror training programme. His comments come in the wake of the three serial blasts that killed 17 people and injured 131 in Mumbai Wednesday.

"Each one of us will have to become a 'policeman' .. look, notice, observe, feel, sense the danger in every step and report," the 68-year-old posted on microblogging site Twitter.

"Yes the security forces will always be needed, but when vulnerable, let each one of us know that we are being watched and monitored. There are many vulnerable nations in the world ... knowing this they have made each citizen of theirs a watch dog, a fighting force!"

"Let there be private or state professional units that take up the job of training citizens in anti-terror acts... make it compulsory. Make that training programme mandatory for every citizen, every national of the country ... I shall be the first to join," he posted.
