A 24-year-old man allegedly posing as a Prime Minister's Office (PMO) official and his armed 'bodyguard' were detained at the Nita Mukesh Ambani Cultural Centre (NMACC) in Mumbai's Bandra-Kurla Complex on Tuesday, where Prime Minister Narendra Modi was scheduled to attend an event later in the day, police said.

Security personnel and police officers deployed at the high-security venue intercepted the duo after noticing their suspicious behaviour. The man could not produce any credentials, police said. A firearm was recovered from the so-called bodyguard, a police official said.

Both individuals were detained and handed over to Mumbai Police for questioning, according to officials.
