MANILA, Philippines?A man was hacked to death with a Samurai sword as he tried to patch things up between two men who were arguing on a street named Peaceful in a depressed area in Quezon City, police4 said Saturday.

The victim, Alvin Afable, died of several hack and stab wounds sustained in the incident, which happened at around 6 p.m. on Peaceful St. in Area 4, in the village of Bagong Silangan.

Police said Afable, 24, was simply trying to mediate between two men having an argument when a brother of one of the men arrived and mistook him for an enemy.

Chief Inspector Benjamin Elenzano Jr of the Quezon City Police District?s Criminal Investigation and Detection Unit said they were able to arrest one of the brothers, identified as Raymund Bongalesa, 29.

Bongalesa?s older brother, 31-year-old Ryan, allegedly came in defense of his brother and mistook Afable as one of the men Raymund was arguing with, Elenzano said.

Initial investigation showed that Raymund and a certain Eugene Estefano were having a confrontation when Afable and his friend Romel Debulgado decided to intervene. But Ryan suddenly arrived, armed with a Japanese-style sword called ?katana.?

The older Bongalesa suddenly attacked Afable without warning, Elenzano said, adding that the victim suffered two stab wounds in the stomach, two hack wounds in the face and a puncture wound in the chin.

Afable was rushed to the East Avenue Medical Center where he was pronounced dead on arrival at 6:49 p.m.

Meanwhile, Elenzano said the two brothers escaped after the hacking but a policeman, PO2 Crismond Rubio, saw the commotion and chased the Bongalesas.

The policeman was able to arrest Raymund but Ryan remains at large.
