A Philippine House committee handling the Resorts World Manila (RWM) attack probe has summoned three other casino operators to check on the condition of security at their venues.

BusinessWorld reported that the Philippine House of Representatives are planning to hold an executive session with other casino operators to determine their “readiness” in the face of security threats similar to what happened in RWM earlier this month.

At least 37 people were killed when problem gambler Jessie Carlos went on a rampage and torched game tables inside the integrated resorts. Carlos then committed suicide by shooting himself in the head.

“I respectfully ask that before we terminate the hearings that we send out invitations to all major gaming casino operators in the country to give this joint committee a full briefing of the state of readiness to prevent a similar event from happening again,” Paranaque Representative Gus S. Tambunting, chairman of the House committee on games and amusement, according to the news report. “This should be done in an executive session to maintain and assure security… After this briefing, we can then consider these proceedings terminated so that each of us can give a report and recommendation to the rest members of the House.”
