MANILA- A total of 40 people were treated by medical teams Tuesday night after the ASEAN Music Festival was cancelled for public safety concerns, the Philippine National Police said.

Metro Manila police chief, Director Oscar Albayalde on Wednesday said of the 40 people reported hurt, 31 were assisted for non-trauma treatments while 9 others for trauma treatments.

The concert, which was staged at the Ayala Triangle Gardens in Makati City, was cancelled after local band "Parokya ni Edgar" initially performed 2 songs.

Albayalde said concert organizers assessed the situation for 2 hours for "health condition," and then decided to discontinue the concert instead.

"After 2 hours of assessing the situation, the concert organizers finally decided not to push thru with the concert for 'reason of public safety,'" Albayalde said.

Albayalde also noted that the concertgoers "voluntarily and peacefully" dispersed at around 10 p.m. after being informed of the concert cancellation.

"The police assisted the NOC (National Organizing Committee) in informing the audience on the cancellation of the concert, making sure that there will be no violent reactions from them. The crowd voluntarily and peacefully vacated the concert venue area at around 10 p.m. with no untoward incident," he said.

Police said around 15,000 people attended the music festival which was secured by over 550 policemen.
