Mumbai Police are investigating the recent attack on actor Saif Ali Khan, which took place in his building. According to sources, the police have reviewed CCTV footage up to two hours before the incident, but no suspicious person was seen entering the building during that time. This suggests the attacker might have already been inside the building before the attack occurred. The police are exploring the possibility that the attacker could have had prior knowledge of the building or was familiar with someone inside. Security measures in the building are tight, and it’s unlikely that an unknown person could have entered without being noticed. The police are also questioning nearby building staff, security guards, and other potential witnesses to gather more information. There is speculation that the attacker may have been someone familiar with the area or had access to the building through connection.
