While 'Mary Kom' filmmaker Omung Kumar does not know much about the incident, he said he got an SMS informing him about her death.
However, filmmaker Vikram Bhatt seemed very disturbed with the news of her death. He said, "She was doing costumes for '1920 London'. She also worked on 'Hate Story 3' and secondary costumes for 'Mary Kom'.
She was a very sweet girl, very diligent, very sincere, a very good friend of mine and a very good friend of my daughter Krishna. I can't believe it is drug overdose. But I don't think she did drugs. I think it could've been a reaction of the medicines due to intake of alcohol."
Calangute police said that Isha was brought dead at a private hospital on Tuesday night and her body has been sent for post-mortem.
