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.

"It's been six days since the victim disappeared but to date the victim's brother, who is also the main suspect, has yet to be called up (by police)," he told journalists in Kuala Lumpur today.

In the incident, Sivaguru was believed to have been beaten up by four men in Jeli, Kelantan, and was subsequently abducted in a black Toyota Hilux.

However, Balakuru managed to trail the two-vehicle entourage before the Hilux stopped.

The driver of the Hilux then allegedly introduced himself as a police officer.

Gobind said Sivaguru's family wants to know who is the real owner of the vehicle and also pressed the police to give an update on the case.

"The victim's family is awaiting the status of the case as it concerns a life," he said.

But Khalid today denied that police were involved in the abduction.

He said that police will investigate the alleged abduction as well as those who "slander" the police by accusing them of being involved in the kidnap.
