Secretary for Security Chris Tang says the government will evaluate the effectiveness of existing laws before considering the need to introduce specific legislation targeting storm-chasing.

He was speaking after four people had been arrested on suspicion of child neglect for taking young boys storm chasing when Super Typhoon Ragasa hit the city last week and a man was summonsed for swimming at a closed-off beach at the time.

Tang said on a televised programme that there are various considerations when it comes to implementing a new law to regulate storm chasing.

"We have also discovered that legislation is not that simple in such a scenario," he said.

"For instance, what places should be declared as prohibited zones, given that every typhoon poses different risks – sometimes it's in coastal areas, sometimes it's from falling trees.

"We also need to consider how we are going to inform the public and how to carry out law enforcement work."

However, Tang also said, the government will not bill any person for any cost incurred during a rescue operation.

This is because it is the workers' duty to save lives, he said, and the administration does not want to see any loss of life from people choosing not to call for help when there is a fine.
