JERSEY CITY - Jersey City's mayor is installing GPS trackers in several city-owned vehicles to keep closer tabs on city employees.

Mayor Steven Fulop's administration decided on the plan after some employees were caught taking vehicles out of the city or letting them idle while taking very long breaks. Last month, a city employee was caught allegedly trying to pick up a prostitute in a city-owned car.

The GPS is hidden in the dashboard and officials will be able to tell if it's been disabled. Fulop says the system will cut fuel costs and improve productivity.
