The Thursday morning arrest came after a police report at around 6am stating that the entrance to the joint office of Legislative Council members Bill Tang and Chan Pui-leung had been splashed with red paint.

Police found that the office, located at the ground floor of Sau Chi House at Sau Mau Ping Estate, had its noticeboard, walls, and metal shutter splattered with paint.

Following an investigation, police arrested the 66-year-old man in Sau Mau Ping on Thursday morning, and he has been detained for investigation. Surveillance footage at the estate shows the man entering a building at the estate, according to the investigation.

The man reportedly claimed his actions were due to the legislators failing to follow up on a complaint he had made earlier.

Condemnation

In a joint statement posted on their social media pages, lawmakers Tang and Chan confirmed that the office had been “vandalised” with red paint. “We strongly condemn these illegal acts and express our gratitude to the police for their swift investigation and arrest,” the statement read.

The lawmakers also said that they had immediately issued reminders and implemented measures to protect the personal safety of office staff and volunteers.

“The office is now operating as usual, continuing to serve the residents of Kwun Tong District and Sau Mau Ping Estate,” the statement continued. They also thanked the public and media for their concern.

Under Hong Kong law, the maximum penalty for a standard criminal damage case not involving intent to endanger another person is 10 years in prison. Cases heard at magistrates’ courts see a maximum of two years’ imprisonment for a single offence.
