The Turkey-trained police force, which consists of 440 policemen, will be responsible for maintaining security across the city.
The new police force in Jarablus has received a 5-week training in the southern Turkish city of Mersin at the request of the FSA, a Turkish official told AA.
For his part, Raed Hamid, Jarablus police commander, said his forces will spare no efforts to maintain security across the city, according to the agency.
Jarablus was liberated from ISIS terrorist group as part of Turkey-led Operation Euphrates Shield, which began late August.
The offensive aimed to improve security, support coalition forces and eliminate the terrorist threat along the Turkish border.
