Police open fire at suspected robbery gang
Two unmarked police vehicles collided with a stolen taxi and another car as officers moved to intercept the suspects on Sheung Lok Street.
The force said it believes the men, aged between 20 and 27, were heading to Hung Hom to commit a robbery.
Detectives were also looking into whether the men are linked to jewellery store robberies that took place on Sunday and Monday.
Officers said they seized five knives, a large hammer, masks and gloves from the cars.
