The Delhi High Court on Thursday will resume hearing in connection with the mysterious death of Congress leader Shashi Tharoor's wife Sunanda Pushkar, at a suite in Delhi's Leela hotel.
The delay in investigation was caused by the delay in de-sealing of the suite.
The hotel suite was finally de-sealed on October 16, three years after the room was sealed for investigation.
The Delhi Police, which was vested with the responsibility of de-sealing the suite, has on several occasions come under the fire of judiciary, for delaying the task.
On October 10, Delhi Police was granted six days to comply with court's earlier order to de-seal Hotel Leela's suite no. 345, as the police reasoned it awaited results from the forensic laboratories.
He has now demanded to make the Enforcement Directorate (ED) a party in the case and the matter has also to be investigated under the PMLA.
Pushkar, wife of Congress leader Shashi Tharoor, was found dead at a suite in a five star hotel in South Delhi on the night of January 17, 2014.
