Ladies of Irving, beware. A serial groper -- or gropers -- is on the loose.

According to an Irving PD news release, at least eight women and girls in recent months have reported "being inappropriately touched on the buttocks" in the southeastern part of the city.

Most of the assaults have happened in the southeastern part of the city on Friday or Saturday morning between 6 and 8:30 a.m. Descriptions of the suspect(s) have varied. Some women they were groped by a man who was tall and slender while others say their assailant was short and heavy-set. Their reports generally agree that the groper is a Hispanic male between the ages of 25 and 45. bald. Some said the man was bald. Others saw him wearing painter's pants and a gray or dark-colored hoodie.

Variations aside, the m.o. is always the same: the man approaches the women on foot, touches their backside, and then immediately runs away. After one of the incidents, a witness saw the suspect driving away in a black 1990s Dodge Ram extended cab pick-up.

Police are encouraging residents to report suspicious activity and avoid walking alone.
