The UP Police on Monday faced rebuke for revealing the identity of Noida gangrape victim with the Centre directing action against erring cops and seeking a compliance report from the state government.

The National Commission for Protection of Child Rights (NCPCR) and UP State Women's Commission have also issued notice to the state government and the police asking them to submit a report.

A fifth person was today arrested in connection with the gangrape of the 17-year-old girl, a student of Class X, who was targeted by the five accused on Friday night on Delhi's outskirts when she had gone with them to a birthday party of one of the accused.

In an apparent damage control exercise, SSP, Noida, Jyoti Narayan told reporters today that an inquiry had been ordered into the issue and "necessary departmental action" would be taken against the concerned personnel.

"Police officers should know that identity has to be protected as per law in certain cases. This kind of attitude by the police is very dangerous," Minister of State for Women and Child Development (Independent charge) Krishna Tirath said while referring to the Noida gangrape case.

The ministry has shot of a letter to the UP government asking it to sensitise police officers about how to handle cases related to crimes against women. Tirath said that her ministry planned to write such letters to all state governments.

In the letter to the UP government, Additional Secretary Sudhir Kumar has apprised the state Chief Secretary Anoop Mishra that the incident was "all the more unfortunate as the identity has been disclosed by those who are themselves responsible for enforcing the law."

NCPCR chairperson Shanta Sinha said, "This is also a cognisable offence and I think UP government must take disciplinary action against the policemen concerned. We have asked for a report and we have if found true, take action."

CPI(M) Politburo member Brinda Karat also demanded stern action against the policemen. "The press release issued by police revealing the identity of the victim is absolutely wrong," she said.

While four youths -- Himanshu Sharma, Rahul Arya, Saurabh and Sunil-- were arrested earlier, their fifth accomplice Neeraj was nabbed on Monday.

All the five were produced in the district court and remanded in judicial custody for 14 days.

Neeraj was arrested from Sector 53 area.

The victim, meanwhile, alleged that she was raped by one of the accused on an earlier occasion also and the culprits had "done the same" to one of her friends as well.
