According to police officials, they have stumbled upon fluid marks on the bed and the carpet and a broken glass in suite number 345 of Leela Palace hotel here which will be now sent to Central Forensic Science Laboratory (CFSL) for examination.
"We have found a broken glass from the crime scene and collected traces of fluids mark on the bed. These fresh evidence will be sent to CFSL," said a police officer.
The recovery, however, raises questions over the investigation so far as to why these things were not picked up when the "crime scene" was first inspected on January 17.
The suit of the five star hotel had remained sealed from that day and was opened for the first time recently.
The investigations were initiated after AIIMS medical board in its second report confirmed poisoning as the reason behind her death, which has been their earlier stand too, but said that the details of the crime scene were not shared with them.
The doctors have not specified the kind of poison and how it reached inside Sunanda's body.
The panel had also advised police to get the bed sheet and pillow of Sunanda forensically tested.
The medical board concluded that Pushkar's vital organs like kidney, lungs and liver were functioning normally and that her death was caused by poisoning.
Delhi Police Commissioner BS Bassi had said the fresh reports submitted to them were "inconclusive" and "based on conjecture".
