Police in Hong Kong arrested 36 people, including a 12-year-old, on Sunday, following a violent protest. Demonstrators have been filling the streets for more than two months, calling for democratic elections and investigations into use of force by police. Tens of thousands of people marched peacefully earlier in the day, but at the end of the rally, some protesters broke away from the crowd at Tsuen Wan Park and started setting up traffic barriers in the road. Police responded, putting up warning flags and then using tear gas to get the protesters to leave. In response, demonstrators threw bricks and gasoline bombs toward the officers, The Associated Press reports. After the remaining protesters, holding sticks and rods, started chasing officers down the street, police pulled their guns on the group, with one firing a warning shot.
