Police arrested six members of a hard-line Hindu group on Saturday for attacking and cutting the hair of three couples on Valentine's Day near the Taj Mahal - India's white-marble monument to love. Meanwhile, members of another group vandalized a shop selling Valentine's cards and raided a restaurant looking for romantic couples in the Indian portion of Kashmir. Public displays of love are frowned upon by the older generation in India. Kissing, holding hands and cuddling are all social taboos, though the influx of Western culture has made it a more common practice among younger couples. The protesters used scissors to cut the hair of overtly romantic young couples in a park in the northern Indian city of Agra, said superintendent of police V.P. Ashok. "The six belonging to Shiv Sena group were arrested for causing a breach of the peace," he told The Associated Press.
