Alachua County deputies say they arrested a man for attacking a dog owner with a tennis ball launcher last night.

Deputies say Thomas Phillips was walking his dog without a leash at the Lake Crossing Apartments when his dog ran up and began attacking another dog who was on a leash.

Deputies then say that dog pulled out of its collar and leash, at which point the other dog owner swung the leash at Phillips's dog to get it to let go.

"He said he began to strike the other dog, trying to get the other dog to stop attacking his dog, when the suspect came over with a tennis ball thrower and hit him across the forehead," said ASO spokesperson, Art Forgey

Deputies say the attack left the other dog owner with a cut and swelling, but no serious injuries.

Phillips is in the Alachua County Jail.
