A police chief's daughter has been convicted of assault but acquitted of the most serious charges in a violent attack on a gay couple in Philadelphia.

A jury on Friday acquitted Kathryn Knott of four counts, including aggravated assault on each of the victims. She was convicted of simple assault and reckless endangerment.

The 25-year-old Knott told jurors she never shouted slurs or threw a punch in last year's assault that left one man with a broken jaw.

Two co-defendants are on probation after pleading guilty.

Several witnesses say Knott is the woman in the white dress who threw a punch during the group attack.

Prosecutors said her earlier tweets show she hated gays.

City leaders have since expanded their hate crime law to include sexual orientation.
