A woman accused of cutting a taxi driver and pulling a gun during a carjacking in Philadelphia's Lawncrest section was arrested in Montgomery County on Tuesday night.
What the Philadelphia woman likely did not realize was the taxi was equipped with GPS.
Police say 29-year-old Toni Williams pulled a knife and placed it on the taxi driver's throat after she entered the rear seat of his taxi.
The driver, who had been dispatched to the 700 block of Adams Avenue about 7 p.m., grabbed the knife with both hands. He sustained cuts to his hands in a struggle, then surrendered his taxi after Williams allegedly pulled out a gun.
Williams, of the 5200 block of Montour Street, was arrested at Huntingdon Valley Shopping Center in Abington a short time later after Philadelphia air and patrol officers tracked the taxi to that location.
Williams is being held on several charges related to the carjacking and weapons.
