Vishwa Hindu Parishad (VHP) on Friday submitted a list that, it said, contained names of the "victims of love jihad" to the chief minister Virbhadra Singh.
The right-wing organisation has been alleging that Hindu girls were being proselytised after being lured into marriage by men of other religions.
Also, in a memorandum submitted to Singh, the VHP has named some groups, including 23 non-governmental organisations (NGOs), which it accused of allegedly converting Hindu girls and demanded that a fresh mechanism be set up to put a check on the trend.
VHP leader Manoj Kumar said the law to check "illegal conversion" had been challenged in the high court which abolished certain provisions from it. "According to that provision before converting to another religion one had to inform the local deputy commissioner, but the court abolished that clause," he said.
VHP women's wing leader, Rajni Thukral, said, "When there is no such provision which were check on illegal conversion, government should devise new mechanism."
VHP also raised the issue of Bangladeshi infiltrators with the chief minister and claimed there were over 40000 Bangladeshi nationals in the state. "Population of Muslims and Christians has gone up surprisingly, which shows some organisations and people are indulging in illegal conversion, which should be checked," Thukral said.
