The incident happened on Monday night in Sahibabad Police Station area after the girl and boy were booked by police under section 294 of IPC (obscene songs).
"Police have misbehaved with me and that is why I reacted. If a person is abused repeatedly then that person has right to object and right to argue also. If they call me a prostitute, then one should argue. I am not a prostitute and nobody has the right to speak to me like that," the girl retorted.
TV footage showed a woman in plain clothes slapping the unidentified girl following which she hit back and was caught hold of by other policemen present.
SHO Ramnath Yadav said that the duo, who were from Delhi, were found near Vikram Enclave creating nuisance and police was informed about it.
"When brought to the police station, the girl spoke in filthy language. The girl and the boy were subjected to medical test which confirmed that they had consumed alcohol," he said, adding that they were booked under Section 294 of IPC which was a bailable offence.
Reacting to the incident, Mamta Sharma, NCW Chairperson, said, "She must not be drunk and even if she was drunk then the police had no right to slap her. The police could have waited for her to get back to normal."
She demanded that the Uttar Pradesh government to take action on this incident.
Former IPS officer Kiran Bedi said, "I think this is the part of the sub culture and that sub culture of using abusive language or slapping needs to change."
