The bodies of two Japanese men fatally shot on a street in Manila last month arrived at Tokyo's Haneda Airport on Wednesday.

According to Philippine police and other sources, the two were Hideaki Satori, 53, and Akinobu Nakayama, 41. They had frequently visited the Southeast Asian country.

The two, who lived in Tokyo, were robbed on the night of Aug. 15, shortly after leaving a taxi near their hotel in Manila. They were shot and their belongings were stolen.

The Metropolitan Police Department said the bodies will be taken to the Hikarigaoka police station in Tokyo for examinations and judicial autopsies.

As it is suspected that a Japanese ringleader ordered the killings, Tokyo police will work with Philippine authorities to conduct further investigations.

On Aug. 18, Philippine authorities arrested 50-year-old Albert Manabat on suspicion of carrying out the shootings, along with his brother Abel Manabat, a 63-year-old tour guide.
