Three illegal immigrants were arrested in Ontario County Saturday after a routine traffic stop on County Road Four. Ontario County Sheriffs deputies pulled over a car in the Town of Seneca for failing to stay within the lanes. When the car was pulled over, police say the driver of the vehicle and two other passengers admitted to being in the United States illegally. Eugenio and Wililbaldo Bravo were taken into custody and turned over to border patrol agents. The driver, Ervin Bravo, was charged with DWI, several other vehicle and traffic violations; he also faces possible illegal entry charges.
