Towson, MD - Baltimore County police are reviewing the arrest of a young man outside a bar in downtown Towson early Saturday after a video of the incident, showing officers taking him to the ground and punching him repeatedly in the face, showed up online."We are reviewing this use of force," said Elise Armacost, a police spokeswoman. "It is not uncommon for officers to use force against subjects who resist arrest, as appears to be the case here."The video, taken by a bystander on the street outside the Greene Turtle on York Road, begins just before an officer yanks 19-year-old Zachary Blumenstein to the ground by the arm and climbs on top of him. A second officer rushes over and appears to drop his knee onto Blumenstein's head.A third officer then grabs and holds Blumenstein from behind, and the second officer punches Blumenstein in the face at least seven times.Police said Blumenstein had tried "to engage another unknown male subject in a physical altercation" and began to "yell profanities at this unknown male." An officer ordered him to leave the area, police said, but he remained and continued to yell at the unknown male and the officer.An officer saw Blumenstein push another male onto York Road, police said. The officer tried then to arrest him, but he resisted, police said. Officers used pepper spray twice in the effort to subdue him.Read more www.baltimoresun.com/news/maryland/bs-md-co-towson-arrest-vi
