In a petition in the Principal Sessions Court, Ernakulam, police said the DNA test has to be done on them to compare saliva sample from the cigarette butt collected from a flat from where they were held and their blood samples to scientifically prove that the actor and the women were using cocaine cigarettes.
The other accused are models and an assistant director from Bengaluru.
Police, who raided the flat, had found six cigarette butts.
Police said they have approached the court seeking further test in a well-equipped lab. They, however, refused to divulge more details.
