BROOKLYN - Shattered glass lined the streets in Fort Greene where roughly two dozen drivers woke up to find their cars broken into. 

About 20 cars were vandalized along Park Avenue, spanning several blocks directly underneath the Brooklyn-Queens Expressway. 

Police say that in all cases, the vehicle's driver or passenger side window was smashed in. Some people also reported their GPS devices, cash, clothing or other items stolen. 

Cops have not yet determined exactly how many vehicles were damaged. No arrests have been made and the investigation is ongoing.
