Nitin Dwarkadas Kapoor, husband of Telugu actress Jayasudha and a cousin of Bollywood actor Jeetendra, committed suicide by jumping off his flat at Andheri, the Mumbai police said on Tuesday.
Police filed an accidental death report soon after the incident around 2 pm.
Visiting Mumbai for treatment for depression for over a year, Nitin, (58), was staying at Sea Glimpse Apartment's 6th floor flat in the upmarket Four Bungalows area with his sister.
For the past few weeks, he was under treatment at the Kokilaben D. Ambani Hospital, Versova.
On Tuesday afternoon, he went to the building terrace and jumped down to his death.
His family living in Hyderabad has been informed.
Police said nothing suspicious has been found so far in the case.
Kapoor, a film producer himself, married Jayasudha in 1985. The couple has two sons.
Jayasudha was a popular Telugu heroine in the late 1970s and 1980s, who has acted with several heroes, including NTR, ANR and Chiranjeevi.
Jayasudha, a Congress MLA from Secunderabad in the previous united Andhra Pradesh Assembly, lost the 2014 polls.
She joined the TDP in January last year.
