The Washington Nationals ended their baseball season months ago, but there was unscheduled excitement this week at their stadium.

D.C. police said they made a an arrest late Wednesday night inside Nationals Park, in an incident that began when an officer spotted a car that was reported stolen the day before Christmas.

Police caught sight of the vehicle on the Southeast Freeway, at locations in Anacostia, and then headed north on South Capitol Street. Finally, the driver got out of the car and ran toward the ballpark, police said.

The Nationals played their last home game Sept. 25. The new season does not begin until April. In the silent chill of a late December night, the stadium’s thousands of grandstand seats were empty.

However, police said, the suspect “jumped the fence” and entered the huge structure.

Officers from the 1st District ringed the building and a dog team was summoned, police said. The suspect was found “hiding in a public restroom.”

Police said they made an arrest on a charge of unauthorized use of an automobile.
