Police Force - Wang Chung (1973) - Lam Tin Estate, Kwun Tong

Next up, Wong goes on a one man raid against a group of gangsters who are tooling up on a rooftop. This was filmed on top of one of the blocks of the old Lam Tin Estate. The first image shows Wong and side-kick (Fung Hak-on) standing on Kai Tin Road with Block 11 behind them. The small block was the fomer Pooi Shing Primary School. 

Judging by the angle on Kwun Tong Police station - which also features in the sequence when a bunch of cops are sent in as backup - then it looks like the rooftop fight was also filmed on top of Block 11. The whole estate underwent a staged demolition that was completed by 2002 and new blocks built to replace the old ones. In terms of the current area, Kai Yan House of the Kai Tin Estate, and the neighbouring carpark occupy the site where Block 11 used to stand.
