Shia Militia forces, which took part in the operations to liberate Tikrit from Islamic States of Syria and Iraq (ISIS) extremist forces, have now left the city.
The head of Tikrit City Council, Ahmad Karim, confirms that most of the militia forces have now left the city.
Following the liberation of Tikrit, a number of local reports indicated that the militia forces had begun revenge killings and looting.
Following the reports, Iraqi President Haider Al-Abadi met with officials of Salahedin Province and stressed that the militia forces had to leave the city.
Sunni politicians report that the situation has become calmer now that federal officials and the local police force have taken control of establishing security in the city.
About two third of the forces that participated in the operation to free Tikrit were armed Shia Militia forces rallied by top Shia cleric Ayatollah Ali Hosseini Sistani.
Tikrit, the capital of Salahedin Province, is 130 kilometres north of Baghdad and connects the capital to Mosul. The city is often regarded as the heart of Sunni Iraq.
