MANILA - Ozamiz Vice Mayor Nova Princess Parojinog-Eschavez and her brother were arrested Sunday in a series of raids that left dead their father Mayor Reynaldo Parojinog Sr. and at least 11 others.

Clad in a black shawl, the vice mayor was visibly composed as she and her brother, Reynaldo Jr., faced reporters at the Ozamiz police station.

Photos from ABS-CBN News' Rod Bolivar show the siblings in an embrace with another relative who brought them food.

The siblings however declined to give media interviews.

Just hours before this, authorities simultaneously served 6 search warrants in the properties of the Parojinogs in San Roque Lawis, Ozamiz City.

About P1.4 million, half a kilogram of suspected shabu and several firearms were recovered from the vice mayor's house. Authorities also seized a firearm from her bodyguard, Nicolas Alburo.

Security personnel at the mayor's house, however, fought authorities and triggered a gun battle that killed at least 12 people.

Among the fatalities were the Parojinog patriarch, his wife Susan and Misamis Occidental Board member Octavio Parojinog Jr.

A neighbor of Mayor Parojinog, identified as Jerrex Lamurin, was brought to the Ozamiz police station for investigation.

Lamurin sustained 2 gunshot wounds during the raid. He denied any hand in the firefight, saying he was only sleeping outside their house.

Mayor Parojinog was one of the local government officials named in President Rodrigo Duterte's narco-list. His daughter meanwhile, was reportedly in a relationship with high-profile Bilibid inmate Herbert Colangco.

The mayor earlier denied any involvement in the illegal drugs trade. -- With Maria Cecilia Butardo and Rod Bolivar, ABS-CBN News
