A Labor Day celebration turns into chaos, sending several people to the hospital and landing one man behind bars.

It happened Monday around 4 in the morning in an East Chattanooga neighborhood. Police say it all started when one guest showed up uninvited to the party.

There was a crowd of people hanging out at a home off Fourth Avenue grilling out on Labor Day. Witnesses say that is when Edwin Ammons showed up uninvited, and he literally crashed the party.

"It made a big ol' bang. That's what woke me up," says Wayne Aaron.

Aaron says his Labor Day was much more eventful than he expected. He woke up early to the sounds of yelling and fighting next door.

"There was, you know, there was a bunch of them out there," says Aaron.

Chattanooga Police say Edwin Ammons showed up at the party where his ex-girlfriend had their son. When she tried to leave, witnesses say Ammons got in his taxi and "floored the gas," ramming his car into her SUV. The SUV hit her and her son knocking them back about eight feet.

"I just heard a big bang. I thought he hit that telephone pole. I finally got up and looked out the window and I saw them all out there fighting," says Aaron.

Ammons then got out of the car with a knife, fighting two other men.

"I just saw them fighting out here and then all at once they told us to call the police. My brother called the police and the police got out here. They had to take him to the hospital."

Ammons was arrested and charged with two counts of aggravated assault, two counts of aggravated domestic assault, child endangerment and reckless driving.

Channel 3 spoke to the victim's mother. She says her daughter and grandson are doing just fine. Records show neither the victim or Ammons has a violent history.

"He shouldn't have done that. That was uncalled for because he could have taken someone's life out," says Aaron.

Ammons is in the Hamilton County jail on a $150,000 bond. He is due in court on September 9th.
