The Gurgaon police have got some clues in the case related to the death of an IPS official.
But senior officials remained tightlipped on the findings of the investigation.
Manjit Singh Ahlawat, who was posted as inspector general of India Reserve Battalion (IRB) at Bhondsi near Gurgaon, died under mysterious circumstances on Saturday night.
He was killed after falling from the fourth floor of Freedom Park Life hi-rise building in Sector 57.
The police got the clue after investigating the Hyundai 120 car which was used by Ahlawat on the day of incident.
Led by DCP (west) Maheshwar Dayal, the investigation was launched on Sunday immediately after the senior IPS official was cremated.
A case under Section 174 of the CrPC has been registered to initiate inquest proceedings.
The police said that the department would take appropriate action after the investigation.
On Tuesday, police officials again visited the spot where the IPS officer had fallen to death and also recorded the entry and exit timings of the deceased.
The police are also looking for a man who accompanied Ahlawat to the fourth floor flat in which a woman lives with his brother.
The officials would also question the brother-sister duo in this matter.
