Two Vietnamese men were injured in a knife attack at a grocery shop at 116 Cheung Sha Wan Road in Sham Shui Po on November 4. Both were conscious and taken to hospital by ambulance.
Shop CCTV footage shows one man entering before another rushed towards him holding two knives. The first man raised a floor fan to shield himself as they struggled.
Customers, including a child, were inside. An adult carried the child out, while other people intervened and took the knives away.
One man had a head wound and the other a hand injury. Police arrested a man on suspicion of assault.
