An 18-year-old man was being held Monday in Salt Lake County Jail in connection with a weekend pit bull attack on a police officer.

Officer David Hendricks shot and killed the dog as it charged at him while he was investigating a report of shots fired near Second South and 15th West about 5:30 a.m. Saturday. He and another officer investigated at a home at 225 S. 15th West.According to police reports, a man ordered the pit bull to attack Hendricks as the officer went around the house and climbed over a back fence. The officer shot the animal twice and killed it.

Two other men then attacked the officers, authorities said.

Bud Ellett, deputy Salt Lake County attorney, said Monday prosecutors were waiting on police reports before deciding whether to file any charges.

One man, the eldest of three, was cited and released for obstruction of justice, the report said. The 18-year-old man was booked into Salt Lake County Jail for investigation of aggravated assault on a police officer, assault, possession of paraphernalia and on a speeding warrant. A third man, age 26, was booked for investigation of assault on a police officer and on an outstanding vehicle registration warrant. The 26-year-old was released during the weekend on $1,000 bail. The 18-year-old was being held without bail.

Hendricks and Officer Robert Hawke were treated for minor injuries at Holy Cross Hospital and released.

The three men were treated for minor injuries at LDS Hospital and released to police.
