Tung Chung station and a number of other MTR stations may remain closed Monday after protestors vandalised machines and equipment today.

Following attacks on 32 stations across the city on Saturday evening, 12 MTR stations sustained damage today.

MTR Corp. described the damage as “very severe” and, without providing any detail, said some stations may remain closed Monday.

It said in the incidents on Sunday, which also included Tsing Yi, Tsuen Wan and Lai King stations that “people damaged CCTVs, ticket issuing machines and add-value machines, took away fire extinguishers and defaced stations.”

Tung Chung was one of the worst hit.

In doubtless the most violent day in the suburb’s short history, protestors arrived late in the afternoon as they retreated from the airport, building barricades and lighting a bonfire on Chek Lap Kok en route.

MTR Corp said it had had to close the Airport Express because of people entering the track and throwing stones and steel bars onto the tracks.

The protestors entered Tung Chung station and attacked ticket machines, sprayed graffiti and flooded the floor with water.

Some entered the Station Control Room, forcing staff to evacuate, MTR Corp said.

By the time police arrived in force at around 6:30pm most had departed.

Many were reported walking on the freeway towards Sunny Bay and the toll booth, where according to social media posts they were picked up by private vehicles.

Citigate mall and Fu Tung Plaza closed down following the incident, while local bus services were terminated at North Lantau Hospital.

Numbering about 200, riot police made a brief patrol around the MTR station before departing at 7:45pm.

MTR Corp said following the damage caused on Saturday night, Prince Edward and Mongkok stations were closed for repairs on Sunday morning while Kowloon Bay did not open until 4pm.
