The incident took place near the Nita Mukesh Ambani Cultural Centre in Bandra Kurla Complex (BKC), close to the Jio World Centre where Modi was scheduled to inaugurate the Global Fintech Fest 2026.
Police identified the alleged fake PMO official as Rohan Parekh.
A gun was reportedly recovered from the man accompanying him, who was allegedly presented as his bodyguard.
Fake PMO identity card raises security concerns
According to police, security personnel stopped and questioned the two men after examining the identity card produced by Parekh.
The card was allegedly found to be fake, following which the two men were detained.
The presence of a firearm with the alleged bodyguard has added another layer to the security concerns surrounding the incident, particularly given its proximity to the venue of a major event involving the Prime Minister.

The Mumbai Crime Branch is now investigating how the two suspects managed to reach the high-security area.
Investigators are also examining whether the alleged attempt to gain access using a forged PMO identity card and carrying a weapon had any connection with the Prime Minister's scheduled visit.
The circumstances surrounding the suspects' movements and their alleged credentials are expected to form part of the investigation.
