Actor Rakul Preet Singh was questioned for four hours in Mumbai today in a drugs case linked to actor Sushant Singh Rajput's death. She was to be questioned by the Narcotics Control Bureau (NCB) yesterday, but it was deferred to today after she claimed she had not received "the alleged summons". "Rakul Preet Singh's statement was recorded by the SIT (special investigation team) today. It will be analysed and produced before court," NCB Director General Mutha Ashok Jain said. Actor Deepika Padukone will be questioned tomorrow. Her manager, Karishma Prakash, was interrogated today and she is likely to be called again tomorrow. Karishma Prakash's questioning went on for much longer than Rakul Preet Singh's, which lasted four hours, sources said.
