Philippine prison brawl kills inmate due to testify against Duterte rival

A riot broke out at a Philippine prison on Wednesday, killing one inmate and wounding three, all of whom had been expected to testify at a congressional inquiry on alleged criminal activity by the president’s biggest critic.

Rolando Asuncion, chief of the Philippines’ corrections bureau, said a drug trafficker was stabbed to death in the brawl, and one of the three wounded men, kidnapper Jaybee Sebastian, had been scheduled to give evidence next week. Dates had not yet been set for testimony from the rest.

The inquiry, initiated by allies of President Rodrigo Duterte, will test allegations that his rival, Senator Leila de Lima, a former justice minister, was colluding with prison inmates and taking payments from them to fund her poll campaign.

Asuncion dismissed a suggestion by House speaker Pantaleon Alvarez that the riot could have been an attempt to derail the inquiry, however. “It’s just a plain riot,” he told reporters. “This is just a usual occurrence in prisons.”
