KOLKATA: Four years after the

, the main accused

was arrested in Greater Noida on September 30. However, his long-time girlfriend and Tollywood actress

who was in close contact with Khan while he was still at large, figures nowhere in the chargesheet.

Nusrat and Kader were all set to tie the knot before Sujet Jordon, an Anglo-Indian woman, was sexually assaulted at gunpoint in a moving car on February 6, 2012, by a gang of five men. Kader was subsequently named as the prime suspect. While all the others were arrested by police shortly after the incident, the cops were successful in arresting Kader just a few days ago.

Nusrat was interrogated by Kolkata Police seeking Kader's whereabouts but she denied any interaction with him after the incident. The actress maintained that if he had committed the crime, he must be punished by the court of law.

However, when police raided a hotel in Mumbai shortly after her interrogation, it was found that the two had booked a room together for a day following which Nusrat returned to Kolkata and arranged tickets to Patna for Kader. She, however, denied meeting him when asked by police officials.

Nusrat, who is regularly seen in city's Page 3 events, was not even treated as a witness in the case.

Several lawyers demand that she be arrested on grounds of giving shelter to a criminal and lying to protect a culprit.
