Lawyer Gobind Singh Deo has questioned why the main witness in an abduction case has yet to be called by police six days after the incident.

The kidnapping case had piqued interest after Kelana Jaya PKR secretary S Murali claimed A Sivaguru was kidnapped using a vehicle registered under the name of inspector-general of police Khalid Abu Bakar.

Gobind, who is also DAP's Puchong MP, said the main witness, A Balakuru, who is Sivaguru's brother, managed to speak to the "kidnapper" who claimed to be an officer from Bukit Aman's narcotics division.
