The 55-year-old man, who stabbed three people to death and injured two others last week, is a sex addict, according to his wife, police sources said. Moreover, Chetan Gala mismanaged the finances. Fed up, his wife moved out with their children two months back, the cops added. He blamed his neighbours for the separation of their family and hatched a plan to take revenge. Gala lived with his wife, two daughters and a son. 

The family lived in a one-room, open kitchen flat, on the second floor of Parvati Mansion, in Grant Road East. Since there was no privacy at home, he would often force their children to go out so that he could get physical with his wife. This was the main source of constant fights in the family,” said a police officer.
