OLONGAPO CITY: At least two provincial buses, one allegedly plying the Candon Ilocos-Manila route, and alleged to be used in vote-buying operations were caught in separate areas here on Sunday night, while a riding-in-tandem fired a gun and threw a smoke signal cannister in front of the home of a village chief in Botolan, Zambales.

The still unnamed driver and conductor admitted they were from Nueva Ecija and were only sent to Olongapo on Saturday to pick up passengers from a place and transport them to another area.
