Thai protesters on Wednesday gave Prime Minister Prayuth Chan-ocha a three day deadline to step down or face more demonstrations, but the leader who made the announcement was arrested within two hours.<br /><br />Prayuth had earlier said he was ready to lift emergency measures he imposed last week to stop the protests as a move to "de-escalate" the situation.<br /><br />Tens of thousands of people marched to his offices at Government House. The protesters have been demonstrating for months against Prayuth and to demand curbs to King Maha Vajiralongkorn's powers.
