Shortly after midnight on Thursday a resident of Summerville who lives on East Washington Street came to the Summerville Police Department to report a prowler.  The complainant said that he observed a “tall skinny man” crawling on the back porch of his residence.  The complainant said that it has happened before and sometimes the skinny man beats on the walls of the house with his fists.  The incidents have been going on for several months, according to the complainant.  He said that he believed that the prowler may be someone who lives nearby, but was unable to give any names to police.  Police promised extra patrols in the area and that a copy of the incident report would be turned over to an investigator.
