New Delhi: The Special Investigating Team of Delhi Police probing the death of Sunanda Pushkar, wife of Congress MP Shashi Tharoor, on Thursday interrogated his domestic help.
Sources said Tharoor's domestic help Narayan Singh was interrogated at an undisclosed location in South Delhi. He was interrogated by police at least twice earlier.

Singh, who was in Himachal Pradesh, came to Delhi this morning after investigators asked him last night to join the probe.
His interrogation came a day after a letter, written by Tharoor in November last year to Delhi Police Commissioner B S Bassi, surfaced in which the Congress MP accused investigators of "assaulting" and "intimidating" Singh into "confessing" that they both killed Sunanda.
