A gunman on a motorcycle killed a hard-hitting Filipino radio commentator Monday in the seventh deadly attack on reporters in the Philippines this year, police said.

The gunman sped away after firing several shots at Arecio Padrigao, a commentator at Radio Natin, in front of Bukindon State University in southern Gingoog city, said police Chief Superintendent Teodorico Capuyan.

He said police were investigating.

Padrigao regularly criticized corruption in his radio show broadcast in Misamis Oriental province, about 480 miles southeast of Manila, police official Catalino Rodriguez told ABS-CBN television.

At least six other Filippino journalists have been murdered this year.
