A man with a history of drug abuse fell to his death from a car park in Tuen Mun yesterday, and police are investigating whether he took narcotics moments before he fell.
Lam Kwan-yin, 28, was found lying unconscious in the lane behind the Tuen Mun Distribution Centre in Hung Cheung Road by a security guard at about 4am.
Paramedics declared him dead at the scene.
Police are looking into whether Lam's death was linked to his drug abuse, a detail disclosed by his father. There were no indications that Lam had suicidal tendencies.
Security cameras captured Lam, who was not working at the distribution centre, lurking suspiciously at the car park around five hours before he fell.
"Closed-circuit television footage showed he was in a dazed state and [displayed] abnormal behaviour in the first-floor car park of the building at around 11pm [on Monday]," a police officer said.
He said an autopsy would be conducted to determine if Lam had taken dangerous drugs.
A police spokeswoman said no drugs were found on Lam at the scene, and there was no sign of a fight or struggle. She said the initial investigation found nothing suspicious about his death.
However, officers are investigating why Lam, a renovation worker who lived with his father in Yuen Long, was at the car park that evening.
In a separate case, a 21-year-old drug user was found dead in an apparent suicide at her home in Tin Shui Wai on Monday.
Her mother found her hanged in their Heng Kin House flat in Tin Heng Estate when she came home at around 10.15pm.
The mother told police officers that her daughter was jobless and had been using drugs for a few years.
The city's security chief this week expressed concern about the growing trend of drug use.
