Around 10,000 security personnel have been deployed across the capital as police intensified anti-sabotage and anti-explosive checks to thwart any form of terrorist strikes, including car bomb or fidayeen attacks.

Commandoes of paramilitary forces are also positioned at strategic locations in Lutyens Delhi, including on the Rajpath where President A P J Abdul Kalam will unfurl the tricolour and take salute of the marching contingents on January 26.

Police officials said they have "general" intelligence inputs about terrorist plans to subvert the R-Day celebrations but have not received any "specific threat" so far to target the capital.

Security has also been stepped up at vital places like airport, security installations and crowded areas including railway stations, bus terminals, Metro  stations, markets, cinema halls and places of worship, sources said.

"We are fully geared up to face any forms of terrorist attack. The specialised units like Special Cell and Crime branch are maintaining full-security alert and vigil to check attempts to spread terror," a senior police officer said.

Checking and frisking have been maximised at all entry points with police setting up three layers of barricades to keep a vigil on all those entering the capital in the next three days.
