MANILA, Philippines?Authorities recovered the stolen vehicles of the son of former Ambassador Roberto Romulo and the father of actor Derek Ramsey late Thursday night and arrested two men who admitted having a hand in the series of car theft incidents the past week.

Director Roberto Rosales, chief of the National Capital Region Police Office, identified the suspects as Dale Alimango, 22, and Glenn del Castillo, 31, who were accosted by intelligence officers in Quezon city.

Rosales said his men received a tip from an informant who spotted two sedans, both Toyota Camry models, in Filinvest 2 past 11:00 p.m. Verifying the information, intelligence officers went to the area and waited for another sighting of the vehicles.

The team, led by Supt. Maristelo Manalo, spotted the cars without license plates, prompting authorities to approach the drivers and shed light into the anomaly. But the men purportedly drew their weapons and shot at the police, prompting them to retaliate.

One of the cars with two men allegedly on board managed to escape during the firefight, but police were able to collar the suspects.

Upon initial questioning, Alimango and del Castillo confessed to participating in the crime, and both men identified their accomplices as Ivan Padilla, who also goes by the name of Jimmy, and a certain Christopher.

Both the suspects also led police to where they stashed another vehicle they took, a black Volvo (plate no. ZAX-887) which they parked in Parañaque City, Rosales said.

Police confiscated the suspects firearms, a .22-cal. handgun and a 12-gauge shotgun, ammunition and a pair of license plates (ZNL-415), which authorities checked with the Land Transportation Office as registered to Roberto Romulo.

Authorities also recovered various documents, including a receipt issued to Jose Romulo and a letter-request to airport authorities for a vehicle pass to Roberto Romulo.

Alimango and del Castillo admitted they forcibly took possession of the car from its driver in Taguig city. They likewise confessed to the taking the Volvo in Tagaytay city on Monday, Rosales said.

The firearms were taken to the crime laboratory of the Quezon city police district for ballistic examination, while the cars were being still being investigated.

Rosales said his men are preparing charges against the suspects for violating laws against car theft and illegally obtaining firearms and ammunition.
