Police were looking for a man who may've approached kids on their way to school.  During their patrols, they arrested a registered sex offender.

41 year old Lewis Harrison was arrested near the Iroquois homes housing project Wednesday.  Police say they found Harrison slumped down in his car exposing himself, while watching young kids walk through the area.

Police say he's a registered sex offender from Lexington.  He's been charged with sexual abuse, criminal trespassing and indecent exposure. 

Police won't say if he's the man they were looking for.

The Crimes Against Children Unit is investigating to see if Harrison may have been involved in similar crimes.
