Hong Kong bus horror as syringe planted on Long Win service from airport injures female passenger on Lantau Island
- Detectives launch criminal investigation into incident, which leaves 30-year-old woman needing hospital treatment
- It follows a spate of attacks last summer when needles were planted on seats, causing panic among some passengers

A woman was injured by a syringe on board a bus on Lantau Island on Tuesday, prompting Hong Kong police to launch a criminal investigation.
The 30-year-old passenger was travelling on the Long Win Bus service from Hong Kong International Airport to Yat Tung Estate in Tung Chung when she was hurt at about 8.45am.
Officers suspect the syringe was planted on the seat of the route S64X double-decker, in a deliberate attempt to injure, a move that has echoes of a series of incidents last summer involving sharp objects.

A police spokesman said the woman suffered injuries to her lower left leg, and a 10cm syringe was found sticking out from the seat in front of her. The bus was near to the Tung Chung Fire Station in Shun Tung Road at the time.
The victim notified the 42-year-old bus driver, who called police. The woman was taken to North Lantau Hospital in Tung Chung for treatment.
A law enforcement source said the bus had surveillance cameras and officers would check the footage in an effort to trace the person who had planted the syringe.
