Navneet R, 26, belonging to an affluent family from Yamuna Nagar in Haryana and currently residing in Mayur Vihar, east Delhi, is being questioned about his suspected involvement in the October 14 rape of the 35 year-old woman, they said.

"We are trying to ascertain whether he was involved in the rape case as there are some indications to suggest so," the sources said.

The convent-educated youth was arrested yesterday in connection with the shootout at the centre, they said, adding that he has confessed to his involvement in that case.

The Swiss woman was raped after being abducted in her own car from the parking lot of the Siri Fort Auditorium where she had gone to watch a movie during the India International Film Festival 2003.
