The Kafr Al-Zayat Police Station in the governorate of Gharbeya was surrounded Saturday night until the early hours of Sunday by a group of youths from different political parties and movements.
The protesters demanded the release of ten detainees who were arrested for rioting during Friday protests.
They chanted against the Muslim Brotherhood, President Mohamed Morsi and the Ministry of Interior.
Reinforcements from the Central Security Forces (CSF) were assigned to secure the station amid fears of escalating violence.
Chancellor Abdel Rahman Hafez, the first attorney of the West Tanta Prosecution, had decided late on Saturday to detain the ten defendants for 15 days pending investigations.
They are accused of pelting security personnel with stones causing several injuries, sabotaging public facilities and throwing Molotov cocktails at the police station.
The police responded to protesters with tear gas before arresting ten protesters and referring them to prosecution.
Mohamed Zaghlool, Karim Mahmoud, Mohamed Farouq, Amin Mohamed Kamel, Ali Al-Shora, Mahmoud Abdel Hayy, Mohamed Hussein, Tamer Fawzy, Alaa Gamal and Metwaly Ahmed are the ten detainees, reported state-run Al-Ahram.
In a separate incident, hundreds of police personnel in the Kafr Al-Sheikh governorate closed down the security directorate building and blocked traffic in front of it.
They demanded retribution for police officers killed and demanded security procedures be reconsidered to allow officers be armed; the demands come following several incidents where unknown assailants infiltrated peaceful protests and attacked police.
The protesting security forces also demanded better employment and living conditions. Security leaders in Kafr Al-Sheikh tried to negotiate with them and promised to forward their demands to Minister of Interior Mohamed Ibrahim.
