Salman Khan's bodyguard Gurmeet Singh alias Shera and three of his accomplices have been booked for assaulting a man in Andheri West early Wednesday morning, an official said here.

According to a complaint by a 25-year-old resident of Vile Parle, Akhtar U. Qureshi, when he was driving in his Audi car with two friends on the Link Road, he saw his friend Shera, said Mumbai Police spokesperson Ashok Dudhe.

Shera called Qureshi who was talking on phone, and the duo entered into a heated argument over some issues, around 2 a.m. Shera and his accomplices allegedly hammered Qureshi with a bat and the butt of a pistol and then escaped from there.

Later, Qureshi went to DN Nagar police station and lodged a complaint of assault against Shera and his three accomplices, which resulted in his collar bone being broken. They have been booked under various sections of Indian Penal Code for assault and also under the Arms Act.

The matter is under investigations, Deputy Commissioner of Police Dudhe added.

The high-profile Shera has been a loyal and trusted bodyguard of Salman Khan for nearly two decades, prompting the the Bollywood star to dedicate his 2011 superhit film, 'Bodyguard' to Shera.
