"Banners will be put up at several places in the capital. We have ten mobile teams ready to roam around the city and check that love birds are not involved in obscene ways," informed Sri Rama Sene general secretary Vinay Kumar.

"If couples are found indulged in obscenity, their photographs will be taken and uploaded on websites to let the world know about this," he said.

Kumar said India is the land of Lord Krishna and nobody should compete with him in terms of love and relationship. He said his party has also set up a helpline number – 9891616259 – where women can complain about any harassment.

Meanwhile, Delhi Police Spokesperson Rajan Bhagat said that elaborate security arrangements have been made to ensure peaceful Valentine's Day.

"Those who will indulge in unlawful activities, will be taken to task. Nobody will be allowed to get involved in violence, whosoever he may be," Bhagat said.

"Patrol will be intensified. Men in uniform, civil clothes and female policemen will also keep a vigil," he said. About the outfit's plan to upload photographs of love birds on Internet, Bhagat said, "We will foil such attempts."

Meanwhile, a group of youngsters, who came together through social networking sites such as Orkut and Facebook, have come up with an idea to distribute "Pink underwear" to the "self-styled custodians" of the culture.

The over 3,500-member group is running the campaign against the "moral police". Delhi police commissioner Y S Dadwal had recently warned that Delhi will "not tolerate moral policing".

Areas which can become possible target of the hardliners have been identified, a senior police officer said, adding that security will be beefed up near pubs, malls and parks, besides around the Metro station entrances and cinema halls.

Securitymen will be deployed near University colleges and hostels to ensure that the day passes off peacefully "without any disturbance". "Besides the moral police, eve-teasers will also not be spared," he said.
