A group of Black Lives Matter protesters were demonstrating against the arrest of a 14-year-old boy at a conference against police brutality in the U.S. when an officer decided to go nuts with pepper spray on the crowd.

According to the Guardian:

The incident occurred near Cleveland State University in the city’s downtown where the first Black Lives Matter conference was taking place. More than 1,200 participants spent the weekend organizing and discussing a range of social justice issues.

According to the Greater Cleveland regional transit authority, its officers were taking an intoxicated teenage bus rider to a police station just as the conference was ending about 5pm. A large crowd blocked the squad car and tried to get the youngster out. One of the officers turned and began pepper-spraying the crowd.

Other law enforcement agencies responded, including Cleveland police department. The youngster was taken examined in an emergency medical service unit, and released to his mother about 6pm.

The name of the officer has not been disclosed and no one has been arrested at this time.
