MANILA (2nd UPDATE) - Authorities rearrested a consultant of the National Democratic Front of the Philippines (NDFP) in Quezon City Wednesday afternoon.

The Criminal Investigation and Detection Group-National Capital Region arrested Rafael Baylosis and another New People's Army member Guillermo Roque along Aurora Boulevard corner Katipunan Avenue.

Police operatives said they received reports of suspicious men with firearms in the border of Manila and Quezon City last Tuesday.

Both suspects were arrested after they allegedly tried to escape.

Recovered from the two were 2 caliber 45 pistols, 14 pieces of ammunition and 2 pieces of magazine for the same caliber, cellphones and assorted documents.

Baylosis was released last 2016 to participate in the peace talks. He is believed to be the first NDF consultant rearrested after President Duterte called off the peace talks.

In an interview with ANC, Philippine National Police spokesperson Chief Supt. John Bulalacao clarified that the arrest of Baylosis stemmed from his possession of firearms and not from President Rodrigo Duterte's orders to rearrest all NDF consultants.

"Hindi upon the orders of the President, it was only reported to the CIDG that there were people in possession of firearms in that area and so they initiated intelligence operation until they arrested Baylosis and his companion," he said.

In a statement released Thursday, the NDFP condemned the arrest and detention of Baylosis.

"This illegal arrest and detention of NDFP Consultant Rafael Baylosis is a flagrant violation of the GRP-NDFP Joint Agreement on Safety and Immunity Guarantees (JASIG, 1995)," said NDFP National Executive Committee member Luis Jalandoni.

While the NDFP demands for the release of Baylosis and his companion, it also urged organizations to demand that Duterte respect and implement the JASIG, the Comprehensive Agreement on Respect for Human Rights and International Humanitarian Law (CARHRIHL) and other binding peace agreements.

"President Duterte must not be allowed to kill and destroy the peace negotiations," Jalandoni said.

Baylosis and Roque underwent inquest proceedings Thursday night after being nabbed for illegal possession of firearms.
