Who was Disha Salian, and why is her case being reopened?

Disha Salian, a prominent celebrity manager, was found dead on June 8, 2020, after allegedly falling from a building. Initially ruled an accident, her father now after 5 years claims foul play, alleging she was murdered. A petition filed by Satish Salian seeks a new investigation and demands an FIR against Shiv Sena-UBT leader Aaditya Thackeray.
