Garima Garg, the wife of Assam's cultural icon and renowned singer Zubeen Garg, told NDTV she has not ruled anyone out for alleged foul play in the death of her husband in Singapore. "Whoever were there at the place of the incident, they are under suspicion. We have filed an FIR [first information report]. The organisers, managers, people in the team, we suspect everyone," a visibly devastated Garima Garg told NDTV on Tuesday. She alleged her husband's death was due to negligence. "We have full belief in our legal system, I think it [investigation] will go in a proper way. We have requested a fast-track investigation. We have to know what exactly happened that day," she added.
