Metro Manila (CNN Philippines) — Authorities have confirmed that there is another person of interest in the foiled bombing in Manila – wherein the bomb was eventually left in a trash can near the U.S. Embassy.
Chief Supt. Oscar Albayalde, acting regional director of the Philippine National Police-National Capital Region Police Office (PNP-NCRPO), confirmed Tuesday that the person has been taken into police custody.
Albayalde said the person of interest was invited for questioning yesterday, but he refused to give further details as a manhunt for other suspects is still ongoing.
'Attempted act of terrorism'
On Monday last week, an improvised explosive device (IED) was found in a trash bin a few meters away from the gate of the U.S. Embassy in Manila.
It was found by a street sweeper who immediately informed authorities of the device.
It was safely detonated by members of the PNP bomb disposal unit.
PNP chief Ronald "Bato" Dela Rosa called the incident an "attempted act of terrorism," and said the IED was similar to the one used in the Davao City night market blast in September.
Dela Rosa said the original target was Luneta Park, but the IED had glitches and was eventually thrown away near the embassy.
Two others probed
Last Thursday, two suspects in the bombing attempt were presented to the media.
Suspects Jiaher Guinar, a businessman, and Rayson Kilala alias Rashid, an imam in a mosque in Bulacan, were presented by Dela Rosa on Thursday as two of the five suspects behind the incident.
Both were allegedly members of Ansar al-Khilafah Philippines, a terror group that has pledged allegiance to ISIS. Dela Rosa added the Ansar al-Khilafah Philippines has an existing alliance with the Maute Group.
The PNP Chief said there were two reasons behind the attack of the Ansar al-Khilafah Philippines: to be recognized by ISIS so they will get funding, and to ease the pressure of the government's military offensive against the Maute group in Butig, Lanao Del Sur.
