On election day, rumors began to circulate that a poll worker had destroyed ballots. Ballot vigilantes escorted the poll worker to the nearby police station, but he was quickly let go and continued to work at the polls. As more rumors of ballot rigging began to accumulate, the poll worker was accused of again destroying ballots. Policemen were called and formed a protective line. As the anger grew, protesters began to throw rocks and overturn police cars. At one point, a tear gas grenade was thrown, and two youths, Chiang Wen-kuo (江文國) and Chang Chi-ping (張治平), were said to have been shot dead by the police. By the end of the night, the protesters had burned down the police station.
