NSA may be invoked against 'Nirbhay' gang rapist

Meanwhile, with less than a month left for his release, Delhi Police is contemplating whether  it can book the juvenile under the National Security Act (NSA).

Last Saturday, Delhi police officers held a meeting with senior lawyers seeking legal opinion on whether further detention can stand judicial scrutiny.

The Home Ministry too has sought an opinion from the Delhi Police. The detention under National Security Act can stretch for one year.

The convict, who is now 21, is likely to be released in December when he completes three years in the correctional home.

In September, an Intelligence Bureau report had stated that teenager had been radicalised by one of the suspects of the Delhi High Court blast of 2011.
