MANILA, Philippines – Chaos broke out in the Senate on Wednesday evening, May 13. The complex went on lockdown. Gunshots followed.

Inside was Senator Bato dela Rosa, the former police chief who led the bloody drug war. He now faces an arrest warrant for crimes against humanity issued by the International Criminal Court (ICC).

For Dela Rosa, the Senate had become a safe haven since Monday, May 11, shielded by its walls, and protected by the new leadership of his ally, Senator Alan Peter Cayetano. The new Senate president had vowed not to allow his arrest within the premises of the upper chamber.

On Wednesday afternoon, Dela Rosa went live on Facebook, saying government authorities would arrest him. A few hours later, unrest unfolded.
