Police in Gogrial West, Warrap, have arrested a gunman accused of attacking the county commissioner.

A local radio station reported that the gunman fired 30 bullets into the house of Makuc Aru on Friday, but there were no casualties.

The suspect is a former security guard who was sacked from his job by a telecommunication firm.

Witnesses said the man had quarreled with the commissioner before returning a few minutes later with the gun.
