A fight between a father and teenage son over who would get to use a portable fan escalated into a family brawl, with the father hitting the teenager in the head with a drill and biting him in the thigh, St. Petersburg police say.

The father - identified as Michael Roberson, 52 - was booked into the Pinellas County Jail on Wednesday morning on a charge of child abuse involving aggravated battery with a deadly weapon.

After Roberson and his 15-year-old son got into the fight over the box fan Monday night, the boy's mother tried to intervene, and then Roberson took a swing at the boy, Proffitt said. The boy in turn struck his father in the head with a football trophy, Proffitt said.

Then Roberson bit his son on the right thigh, at which point his son punched him in the back of his head, Proffitt said. The two ended up on the floor, with Roberson hitting his son in the forehead with a Black and Decker cord drill, Proffitt said.

The boy's mother then took the drill away from Roberson, at which point Roberson tried to bite the woman, and her son punched his father, Proffitt said. When Roberson grabbed his son by the throat, the boy's 13-year-old sister pulled him off, Proffitt said. Then the boy called police.
