Incidents between Kurdish protesters and young Turkish supporters of Recep Tayyip Erdogan took place outside Downing Street.
About 450 Kurds protesting in the wake of the Erdogan-May meeting in the afternoon were revived when police tried to disperse pro-government protesters near their home.
The result was minor clashes with plastic water bottles and placard poles being fired from both sides.
The police proceeded to bring at least a Kurdish demonstrator.
