Filmmaker Sajid Nadiadwala's 67-year-old father-in-law was allegedly pushed to death by his nephew from the fourth floor of a Versova building after an argument on Tuesday.
The Versova police arrested the 20-year-old nephew of the deceased, Aziz-ul-Rehman Khan, on murder charges. Khan died during treatment at Kokilaben Ambani hospital the same evening.
According to the police, Khan lived on the second floor in the H wing of Saurabh Apartments with his wife and his son, Mohsin, 29. His three daughters are married and live separately.
Khan's younger brother, Khalid, 50, lives in the G wing of the same society with his wife and two sons - Shahjeb and Keejer, 13.
The police said both families were involved in a property dispute, although no official police complaints had been filed.
Around 10.30am on Tuesday, Khan went to Khalid's fourth-floor residence. Initially, Keejer opened the door and told Khan that his father was not at home. Khan, however, did not believe the boy and waited outside the house.
After a few minutes, he again rang the bell. This time, an angry Shahjeb answered the door and got into an argument with his uncle, the police said.
An agitated Khan insisted on entering the house and tried to barge in when Shahjeb allegedly pushed him.
"Due to the impact of the push, the senior citizen lost his balance and fell over the staircase wall, which is barely three feet away from the door. He fell four floors," said Sharad Bodse, senior inspector, Versova police station.
"Other residents took him to the hospital. Since he fell on his back, he had sustained severed injuries on his head," he added.
The police said Khan slipped into a coma before his statement could be recorded. Shahjeb was arrested under Indian Penal Code section 302 for murder on the basis of a complaint filed by Mohsin.
"Shahjeb has been remanded in police custody till October 15. We have learnt that the two families had a long-standing property dispute and are trying to gather more information on it," Bodse said.
