ALBUEQUERQUE, NM -- A teen is in hot water after he allegedly threw a rock at a police sergeant during a protest outside a Trump rally.Marcus Griego, 14, was arrested in Albuquerque, New Mexico after being accused of participating in a violent spree outside Donald Trump's speech."The commander actually witnessed Marcus throw a rock directly and hit the sergeant that was standing next to him," Albuquerque Police spokesperson Celina Espinoza says.Police say Griego "laughed it off and kinda just pretended it wasn't a big deal."The teen is now charged with two felony counts of aggravated battery on a police officer.The boy's attorney says Griego did go to the Trump protest but denied to parents that he threw the rock.The District Attorney says they will prosecute the 14-year-old as an adult. His attorney says, however, the felony charges are an overreaction.The Albuquerque Police Department agrees."We don't want to make an example out of a 14-year-old," Espinoza says. "We want to be able to guide and lead him in the right direction."The teen is being held at a juvenile detention center. He has no prior criminal history.
