U.S. Park Police and federal officers, including ICE, conducted an enforcement operation on Clara Barton Parkway on Wednesday morning. Three occupants fled a vehicle during the stop; after a pursuit, two people were taken into custody while a search for the third person was called off. No details regarding the identity of those arrested or charges were available. Montgomery County Fire and Rescue responded to search the Potomac River between Lock 7 and Lock 10 out of concern that some fleeing individuals may have entered the water.
