A Japanese national living in Japan is suspected of ordering the killing of two fellow Japanese men in Manila, with a financial dispute being the likely motive, Philippine police said Tuesday.

Authorities said the suspect allegedly hired two Filipino brothers to kill the two men, paying them an initial down payment of 10,000 Philippine pesos ($174) toward an agreed fee of 9 million pesos ($157,233). The brothers — Albert Manabat, 50, and his tour guide sibling, Abel Manabat, 62 — have been arrested over the murders.

Investigators believe the Japanese suspect had traveled frequently to the Philippines and became acquainted with Abel, who served as his driver. Police allege he then asked the brothers to carry out the shooting.
