The carjacking took place at about 4:20 a.m. Monday in the 2700-block of West Lexington Street.
Police said a 26-year-old woman was sitting inside a vehicle with two boys, ages one and six, when two suspects approached.
The suspects implied they had a gun and forced the woman and the one-year-old boy out of the vehicle, police said.
The suspects then sped away with the six-year-old boy still inside, police said.
Police said the six-year-old was later found outside, a short distance away where the carjacking was reported. At the scene, officers could be seen carrying a child from an ambulance.
Police said the 17-year-old was then arrested and now faces one felony count of vehicular hijacking, one felony count of aggravated fleeing police and one felony count of unlawful possession of a stolen vehicle as well as misdemeanor counts of obstructing identification and child endangerment.
