After a preliminary investigation, police said they believed that wire valued at about HK$100,000 was stolen.

The case has been classified as theft and is being handled by the police force’s Tseung Kwan O district criminal investigation unit. No arrests have been made.

Copper wire in a lightning rod system acts as a conductor. The wire creates a low-resistance path, allowing the electrical charge from a lightning strike to travel safely to the ground. This process dissipates the energy and prevents damage to the structure.

The MTR Corp said staff at Po Lam station discovered that a section of the wires installed on the rooftop was missing during a routine inspection of the drainage system and immediately filed a police report.
