From Dragon Ball Encyclopedia
Gyaosu (ギャオス, Gyaosu) is the police chief of the Penguin Village Police Force.
Gyaosu was told by Taro Soramame that someone from the Red Ribbon Army was in town. He and the rest of the police force got armed to take him on. They began to head out, but then were distracted and wasted time taking out King Nikochan's UFO instead.
