A Sergeant has been placed on administrative leave after footage captured during protests in May after George Floyd was killed by police in Minneapolis.
The Boston demonstrations on May 31 were largely until late at night, when riots were declared. More than 50 people were arrested, 18 visitors were admitted to the hospital and nine officers were treated for injuries, Boston.com reported.
In videos released on Friday by the online news agency Appeal, officials said non-violent protesters were being pushed to the ground and sprayed with pepper spray on people and crowds, and an official said he may have attacked people with a car.
The lawyer for the protesters has demanded the video.
Commissioner of Police William Cross said in a statement that he had ordered an investigation as soon as the videos were brought to his attention.
“I have a sergeant involved in this incident on administrative leave and will take the necessary additional action at the end of the investigation,” Cross said. “I want to encourage people to bring these things to our attention so that they can be properly investigated.”
Mayor Marty Walsh said it was difficult to see the footage and hoped the answers would come through the investigation.
“Even when the tensions are high, we never want police officers to use more force than necessary,” he said.
A spokeswoman for Suffolk County District Attorney Rachel Rollins said she is also investigating.
