Hong Kong police have arrested a woman in her 40s who opened fire at her aunts and uncles at Quarry Bay Park on Tuesday (June 26) afternoon.
The quartet aged between 60 and 80 suffered a range of injuries in the gun attack, according to the South China Morning Post.
A man and a woman sustained head injuries, while the other two victims were shot in the shoulder and hand.
A handgun was found at the scene.
"It appears the suspect has a target in the incident," a police source said, ruling out the possibility of the shooter as a terrorism suspect.
