The police have interrogated some suspects in the Hi-Lite Mall incident in which two female actors complained of sexual assault while returning after a promotional event.
Though the police quizzed one of them for hours based on CCTV grab on Thursday, he was found to have no involvement in the incident.
Officers associated with the probe said they were yet to confirm the involvement of anyone based on the CCTV visuals. Since it happened in the middle of a crowd, it would take time to identify the suspects, they said.
