Hundreds of people protested against alleged corruption and illegal labour in Macau. There is a lack of jobs due to influx of cheap foreign labour caused by a recent boom in Macau's casino trade. They accuse the government of ignoring the situation. A protester carried the sign "The government is rich, the casinos are rich, but nobody is looking out for the Macau people." Protesters surrounded a police vehicle and threw water bottles and placards at the officers who fought back with water cannons. Police also fired shots into the air. There were some injuries from the use of the cannons.
