Crackdown on "Romeos" -- a term loosely used for molesters -- was a pre-election promise of the BJP. Yogi Adityanath asked the police to implement it days after he took oath as the Chief Minister of the state on March 18.
On Tuesday, the police said orders have been reinforced not to mete out on-the-spot punishments. Men caught harassing women will not be tarred, forced to so sit-ups, murga punishments -- squatting and holding their ears -- or be tonsured. Instead, legal steps will be taken against them, officials said. The police have also been asked not to harass couples.
Following the lead of Uttar Pradesh, neighbouring Haryana announced the formation of Durga Vahini - police squads that would aim to stop harassment of women on public spaces. But the state government clarified that the police have been strictly instructed not to cause any inconvenience to the innocent.
