Protesters posted photographs and videos of clashes between police and demonstrators and there were reports that tear gas had been used on crowds and that pepper spray had been used against detainees.
“I approached police at demo and asked them to join us! They were thinking for a while. Then Arrested me. Writing from police station,” tweeted Emin Milli on Saturday afternoon.
Up to 100 people were thought to be detained, though initial reports put the number of arrests at around 40.
