Earlier in the day, Sushant's friend Rhea Chakraborty visited the Cooper hospital. Rhea was also present at the funeral.
According to a source, only family and select friends were allowed inside the crematorium in the wake of the coronavirus pandemic.
Meanwhile, the provisional post mortem report revealed that the cause of death was asphyxia due to hanging, Deputy Commissioner of Police Abhishek Trimukhe said.
The actor had been living with two cooks and a house help.
No suicide note has been recovered from his home, the police said.
The post mortem was conducted at the Cooper Hospital in Mumbai.
Bihar Bharatiya Janata Party MLA Niraj Kumar Singh 'Babloo', one of Sushant's relatives, accompanied Sushant's father from his hometown Patna to Mumbai.
If required, the BJP MLA said an investigation would be ordered into the actor's death.
"We still can't believe that he is no more. If needed, we will ask for investigation," Singh told reporters outside Sushant's home in Patna.
