At 8 p.m. Thursday, Nov. 12, a woman was sitting in the grass in the 2500 block of Perryton when a man approached her from behind and ripped off her shirt and bra. She was able to fight him off.

The attacker is described as “light-skinned, medium build and muscular, wearing a black face mask, a dark thermal shirt, and dark jogging pants.” His race and age aren’t known.
