BANGKOK -- Thailand will take steps to ensure safety and restore confidence among tourists, officials said on Wednesday, one day after a shooting at a renowned shopping mall in downtown Bangkok that killed two people and injured five others.

The Thai government has attached great importance to this matter and will implement measures to prevent the recurrence of similar incidents, Prime Minister Srettha Thavisin said after joining a one-minute silence at the mall and expressing condolences to the deceased.

He added that the government will be working on the implementation of an alert system to notify the public about emergency situations.

In a press conference, Tourism and Sports Minister Sudawan Wangsuphakijkosol said that government agencies would work harder to restore confidence among tourists.

The police have encouraged shopping malls and other public places to implement stricter security screening and be constantly prepared by providing training for security personnel, Samran Nualma, Assistant Commissioner-General of the Thai Police, told the news conference.

Investigators initially pressed five charges against the suspected gunman, including premeditated murder, attempted murder, illegal possession of a firearm and ammunition, illegally carrying a weapon, and firing shots in a public place, Nakharin Sukhonthawit, commander of Metropolitan Police Division 6, told reporters.
