The streets of Wilmington witnessed increased police activity last month, culminating in the arrest of a suspect tied to a case of gunfire without casualties. On the night of Halloween, at 5:55 p.m., the Wilmington Police Department responded to a report of shots fired on the 2400 block of North Market Street; luckily, no individuals were struck during the incident, according to a release posted on Nixle, an official communication service for local government agencies.
