KOCHI: Kalabhavan Sobi has appeared at the CBI office in Kochi for a polygraph test in connection with the death of violinist Balabhaskar. The polygraph tests related to the case have been going on for the last 2 days. Earlier, Balabhaskar's driver Arjun, former manager Vishnu Somasundaram and Prakashan Thampi had appeared for polygraph tests.

Reiterating that Balabhaskar's death was a planned murder, Sobi added that the CBI investigation is in the right path. He alleged that a gang smuggling gold to Kerala was behind the death of the violinist.

It was Sobi who said that he had seen a group of people attacking Balabhaskar's car soon after the car met with an accident. Following this, CBI decided to opt for polygraph tests as it found discrepancies in the statements given by four main witnesses.
