After her bold act appeared in the media, she has been showered with phone calls and letters praising the manner in which she handled the situation and a state minister even visited her home to pat the courageous girl.
Following the incident, police registered a case against the two eve teasers.
One of the accused, however, filed a private complaint in a local court alleging he had been beaten up by the girl who also blocked his car.
Admitting the complaint, the court on Monday directed the city police to register a case and investigate the incident.
Meanwhile, state Women's Commission chairperson KC Rosakutty and leaders of various women outfits criticised the action against Amrita, who is widely seen as a symbol of "courageous womanhood".
A black belt in Karate, Amrita said she would legally fight the case against her.
