The Bandra police are questioning two individuals who were carrying out flooring work on the terrace of actor Saif Ali Khan’s residence. Officials suspect that the accused who attacked Saif in the wee hours of Thursday was familiar with the layout of his building, Satguru Sharan, and used the shaft and stairs to access the 11th floor, where the actor lives with his family.

“The accused used both the shaft and the stairs to enter the building and reach the 11th floor. It seems he had knowledge of the premises. We are investigating whether the individuals working on the actor’s terrace have any connection to the incident,” an officer said.
