Everything about that night was usual for the residents of a small rented house on the second floor of a building at Vennala in the heart of Kochi city, until they heard a knock on the door.

It was past midnight, but the family of four – a young man, his live-in partner and two children – were still awake. He opened the door and found a group of men, clad in casuals, at his doorstep. Soon he would learn he was trapped, for the men were members of the District Anti-Narcotics Special Action Force (DANSAF) of the Kochi City police.
