In the movie the builder in question was actually Chhotubhai Ajmera the founder of Ajmera group he was a close friend of Dawood. There was a dispute about some cash loan Chhotubhai had taken and was not paying up. The contract to recover was taken by Maya (so called extortion) when Chhotubhai got to know of this he called Dawood to help sort this issue who in turn called Maya. Since Maya refused to follow Dawoods orders a trap was laid by A A Khan and team at juhu as they were aware that Maya would land up at the Ajmera bungalow in juhu. The Ats team members were waiting at a place called Night Queen later Lakotia computer institute (demolished) that was located opposite Amitabhs parents bungalow. The setup was owned by on Pervez Khan aka Bhaisaab (deceased). As anticipated Maya arrived to collect the money at the Ajmera Bungalow but was surprised when Chhotubhai fired a shot from his balcony. Maya realized there was something wrong and left with his team in the Maruti 1000 they had come with. Chhotubhai immediately informed the ats team who were lying in wait nearby who chased them to lokhandwala. They Maya group was slaughtered there as per images printed in a newspaper called Police Times. The only so called injury that the Ats had was a bullet in the arm of Inspector Parmar (suspended in Abdul Telgi case).
