Police say an argument between parents and a coach at a junior football league practice in Kansas escalated into a fight involving gunfire.

Police say one man complained that his son was not getting enough playing time during Monday evening's practice at Linwood Park in Wichita. Then six men surrounded the coach and started punching him.

Police say one of the parents was armed with brass knuckles and another indicated he had a gun.

Then the coach's wife pulled out a gun and fired a shot into the air. Police say the coach subsequently went to his car where he retrieved a second gun and threatened the men with it.

His assailants fled before officers arrived and confiscated both guns.

No one was seriously hurt and no arrests were made.
