Actor John Abraham and makers of the film Batla house dropped the much-awaited trailer of the film on Wednesday.. The upcoming film is based on the controversial Batla House encounter of 2008. John Abraham, who plays the role of decorated cop Sanjeev Kumar Yadav in Batla House, tweeted: "Was the nation prejudiced or was it really a fake encounter? The questions will finally be answered?" The trailer begins with intriguing glimpses of the encounter with one of John`s fellow cops being shot in the gun battle. Then it swiftly moves on to controversy that followed. The Batla House Encounter, also referred to as "Operation Batla House", was conducted in Delhi`s Jamia Milia locality in September 2008, in which two suspected terrorists were killed and two more suspects were arrested. The trailer also offers glimpses of how John Abraham doesn`t deviate from his version of the truth during several interrogations following the encounter as he is faced with threats such as losing his job or even his loved ones. However, one scene features John Abraham being honoured with the President`s Medal for his contribution in the Batla House encounter. The film will release in India on 15th of August.
