Gwinnett County police have arrested a man who they say flashed two women at Georgia Gwinnett College.

Derrick Williams is charged with public indecency, peeping Tom and home invasion, according to police.

After asking two separate women for directions, a man allegedly exposed himself to them on the campus, the college said Friday.

The first woman told campus police she was walking to her car in the L Gravel parking lot between 1 p.m. and 1:30 p.m. Thursday when a man sitting in a car asked for directions to Sugarloaf Mills mall, the college posted on its Facebook page.

When she approached the car, she saw the man touching himself, she told police. Campus police searched the area, but could not find the suspect or his vehicle.

Then, between 1:20 p.m. and 1:30 p.m. Thursday, a woman reported a similar incident in the A Building parking lot. This time, the suspect asked for directions to Walmart before exposing himself to the woman, according to police.

Williams is being held in the Gwinnett County jail.
