Massachusetts State Police said Wednesday they were still attempting to contact the man who posted a video to YouTube that appeared to show a trooper using pepper spray on a protester in Boston.Kin Moy, interviewed by NewsCenter 5 on Sunday, said he was videotaping arrests Thursday at the Boston protests for two recent grand jury decisions to clear police officers involved in the deaths of Michael Brown and Eric Garner, when a state trooper used pepper spray on him.Moy caught the incident on video and uploaded it to Youtube, where it accumulated more than 15,000 views by Wednesday.State police said the trooper depicted in the video was placed on restricted duty Tuesday as the department conducted an internal investigation into the incident.Police said the name of the trooper would not be released while the internal investigation was conducted.The video shows police attempting to move protesters back during protests Thursday night in Boston.A trooper in the video can be heard saying "Go, now, you're going to get sprayed."The trooper then appears to point a canister toward Moy.Moy then turns the camera to show a liquid covering the side of his face. He said the reaction of state police in his case serves as an example of the tension currently felt across the country between protesters and police."It was very painful at the time," Moy said. "When the officer pepper sprayed me that was an example, to a much less extent because I am still alive, but it was using force that exceeds necessity."Moy said he was following the trooper's instructions to move away."I had no intention of going head to head with officers, I was backing off," Moy said.State police said they have attempted to contact Moy by leaving comments under his video on YouTube and also sent two Internal Affairs investigators to try to speak to him at his residence as well as at a local gym.Police said messages and contact information were left at both locations.Moy said Sunday he had planned to meet with a lawyer, as well as the American Civil Liberties Union, before contacting police.
