Officers found 44-year-old Bobby Riggs Williams screaming and making racial comments toward David Burke when they arrived to the 10400 block of Ebbitt Road about 11:15 a.m., according to the arrest report. Williams is black.

The neighbor, whose age and race were not listed, told police he took out a pocket knife for protection after Williams threatened him about grass clippings that were blown onto his property, the report said.

The neighbor said Williams got a machete from his car and returned raising it toward him and threatening to kill him, the report said. Burke armed himself with a second small knife and told Williams to leave, which he eventually did.

When police tried to get Williams to come outside his chain-link fence, they said he refused and repeatedly said he would release his dogs to attack, the report said.

By about 2 p.m. officers were able to get Williams to leave his property. He was charged with aggravated assault with a deadly weapon, aggravated assault on a law enforcement officer and resisting arrest.
