Commenting on the Sunanda Pushkar murder case, BJP leader Subramanian Swamy on Thursday said that it was time for Shashi Tharoor to come out with the truth.

"I am happy that the process has started. I was going to file a PIL on January 15, but now I don't have to so I am happy. The truth has already practically come out. It is now for Mr. Shashi Tharoor to speak the truth," Swamy said, according to a Zee News report.

"I am very pleased with both the Home Minister Rajnath Singh's decisiveness and with some of the doctors of the All India Institute of Medical Sciences (AIIMS) who stood their ground and resisted pressure from the previous government," he added.

Meanwhile, Tharoor's domestic help Narayan Singh, interrogated by Delhi Police twice earlier, was on Thursday called for questioning, police said.

The special team took Singh to an undisclosed location in south Delhi, an official said.

On Wednesday night, Tharoor's staff received a notice from police asking Singh to join the probe.

"Narayan was in Himachal Pradesh. He came here today (Thursday) morning and left for the police station," a staff member at Tharoor's residence told IANS.

Police Commissioner B.S. Bassi said they had not sent any legal notice to Tharoor to join the probe yet.

Tharoor had claimed last year that Delhi Police had pressurised his domestic help to name him as his wife's killer.

In a letter written exclusively to Headlines Today on 13 November 2014, the former union minister had complained to Bassi about the Investigating Officer's intimidation and assault of his help.

Following are the excerpts from the letter:

"In the course of the interrogation conducted by Delhi Police officers... my domestic help, Shri Narayan Singh was repeatedly physically assaulted by one of your officers. Worse, that officer used the traumatic physical assault to try and intimidate Narayan into "confessing" that he and I had murdered my wife."

On Tuesday, Delhi Police had changed the Sunanda Pushkar death case from suicide to murder.
