Bangalore Metro Rail Corporation — misbehavior by a metro male frisking staff to a woman

Address: Hosahalli Metro Station, Bangalore, Karnataka

I entered Hoshalli metro Station at around 5.00 PM in the evening. This is about the frisking guard who is positioned at the entrance. Basically, as you enter you are met with the males' frisking booth, and females are required to ascend the stairs. I'm a FEMALE. I blankly stared at him and walked away.
The next day, I'm yet to set foot inside the metro station and the same guard from the previous day, stops me and keeps calling me! And NOW I KNOW THAT HE IS UNABASHEDLY TEASING! All the spectators around me are also calling out to me: "Oi!", they shout to me, probably assuming me to be a security threat, the shameless guard has managed to ruin my reputation and legally speaking (I'm a law student), he is indisputably liable for defamation and the Indian penal code for outraging the modesty of a female. I continue my way, ignoring all of them.
I hate his behaviour, and if I see him again tomorrow, I will lodge an official complaint with the metro station and the police.
The incident may seem inconsequential, but it is not! And thus, what I've been experiencing for the past 3 days, at the Hosahalli metro station, from same male frisking guard is nothing short of causing harm to others and specially women who have to walk on egg shells to protect themselves. Such behaviour is invariably capable of hurting someone's self esteem. More than that, I was humiliated!

Take suitable action against such pathetic and outrageous male frisking guard.
