Hundreds of protesters in Hurghada blocked several main squares on Tuesday using iron barricades and burning tires.
The demonstrations were prompted by burial of young man Tuesday, who died in a fight over money between the owner of a property and the person renting the space.
The family of the victim held banners, demanding justice and retribution for his death.
Protesters barred vehicles from passing through al-Saqala, al-Arousa, Aka and al-Dahar Squares as well al-Sheraton al-Siyahy and al-Sayadin Streets. They also barred people from entering or exiting the city's marina.
Mohamed Attiyat Allah, the Wasat Party's secretary in Hurghada, said quick justice would resolve the issue after police failed to convince protesters abandon their sit-ins.
