The attack on Khan has made national headlines and also raised questions about safety and security in Mumbai, one of India’s most populated cities and its financial capital.

Khan was stabbed six times and suffered several injuries, including one on the back of his neck, in the attack at his home in an upscale neighbourhood.

A nurse, Eliyama Philip, who works in Khan’s home, told the police last week that she first noticed the shadow of a man near the bathroom door late at night while she was in the child’s room with the nanny.

Ms Philip said a man appeared holding a wooden object in one hand and a long blade in another and warned the two against making any noise. He demanded 10m rupees ($115,477; £94,511), she said.

A scuffle broke out, during which Ms Philip was injured. She also said that hearing the commotion, Khan and his wife rushed to the room and that the attacker struck the actor with a blade before fleeing.

On Friday, investigators reportedly detained – and later released – at least five other people for questioning in connection with the investigation.

Many of the men were taken into custody because they resembled the attacker, who was captured on CCTV camera while he was exiting the building.
