With terror threat still looming over the city, the Mumbai police, who are on their toes, on Wednesday detained a person with an AK 47 but later it turned out to be a dummy weapon.

Policemen attached to Oshiwara police station went to Anand Nagar at Jogeshwari in western suburbs in connection with a case when they saw a person moving about suspiciously, wrapping an object in a cloth.

"Our men intercepted him and asked him to show the object he was hiding in the cloth. They found that it was an AK 47. He was immediately brought to the police station," said

Dattatrai Sankhe, police inspector of Oshiwara police station.

However, when police checked the weapon it turned out to be a fake AK 47, which is used in film shootings.

"Nirupam Nadva, 26, who has been detained, is claiming that he is into shootings. We are questioning him to know further details like whether he is into films or serial shootings, where he headed with the dummy weapon, why he was carrying it," said the official.

Nadva is likely to be let off after questioning, police said.

The taxi was found parked near the Municipal Corporation of Greater Mumbai headquarters and the Times of India [Images] building following which the Bomb Detection and Disposal Squad was called in, they said.

After thorough checking, the vehicle was found to be empty and declared safe, police said.
