A week after the US authorities expressed willingness to help probe actress Jiah Khan's death case, they have assured her mother Rabiya Khan that a reminder would be sent to Indian officials offering their assistance, her lawyer said today. Rabiya had on Wednesday said she would move the Bombay High Court seeking a reinvestigation of the case by CBI or a Special Investigation Team from the angle of possible murder after Mumbai police charged actor Suraj Pancholi with abetting the British-American actress's suicide.
