Activists in Turkey have called for the sacking of police chiefs in Istanbul, Ankara and other cities over their forces' violent responses to protests.
They presented a series of demands to Deputy PM Bulent Arinc, who on Tuesday apologised to injured protesters.
Thousands of striking workers have joined demonstrations to demand Prime Minister Recep Tayyip Erdogan resign.
