Turkish government has lifted a ban on female officers who wear the Islamic headscarf.
Policewomen will be allowed to wear the Islamic headscarf under their caps or berets, provided it is plain and is the same color as their uniform.
Hijab bans on universities and state institutions, except for the military, judiciary and police, have been lifted in recent years.
Secularists regard the garment as a symbol of religious conservatism, therefore it has been controversial in Turkey for years.
Since 1920s, Turkey has become known as a secular state with no state religion.
Secularists have been accusing Turkish President Recep Tayyip Erdogan and his Justice and Development Party (AKP) of trying to reinterpret secularism and promoting Islam in the country.
Public opinion, however has evolved to accept the Islamic headscarf as an expression of individual liberties.
Erdogan has supported Turkish people's rights to express their religious beliefs openly, but at the same time he says he is committed to secularism.
The latest move to lift a ban on hijab has not drawn any strong opposition.
Also in 2010, Turkish universities lifted a ban on Muslim headscarves. In 2013, women were permitted to wear hijab in state institutions, with the exception of military, judiciary and police. Four members of parliament wore headscarves in Turkey's parliament that year.
The majority of Turkish people are Sunni Muslims.
