A loud sound was heard near the Golden Temple in Amritsar in the early hours on Thursday.
Police personnel and forensic team members rushed to the site of the incident and the probe is currently underway.
Further details are awaited on the matter.
Last month, on April 12, four Army jawans were killed in their sleep in the firing incident that took place at the Bathinda Military Station.
The four jawans were identified as Sagar, Kamlesh, Santosh and Yogesh.
They were asleep in their rooms post the end of duty when two masked men, in white kurta pyjamas, attacked them with rifles and sharp-edged weapons. The four jawans were found in a pool of blood in their rooms.
