CINCINNATI (AP) -- Federal, state and local authorities say they have confiscated at least 200 guns and more than 50 pounds of marijuana and made numerous arrests in a sweep of individuals accused of violent crimes in Cincinnati.

They said at least 30 arrests had been made as of Thursday afternoon as they targeted up to 120 individuals. Cincinnati police Chief James Craig says the sweep will continue for several days. Authorities at a news conference displayed the firearms confiscated in three separate investigations over the past few months.

The investigations have been conducted by a new task force of officers from local, state and federal law enforcement agencies, including the Bureau of Alcohol, Tobacco, Firearms and Explosives.

Police say those arrested face various charges involving drugs, weapons and violent crimes.
