Cambridge Police report arresting Alexis Rodriguez-Perez, 28, of Mattapan, in a room at Cambridge Hospital on Monday after, they say, a hospital security guard found two loaded 9-mm magazines stuffed in his pants and a loaded 9-mm gun in a trash can next to his bed.
Rodriguez-Perez had been brought to the hospital "after he was originally found unconscious at a Harvard Square coffee shop bathroom following a reported drug overdose," a police spokesman said. Rodriguez-Perez was about to be discharged - he was awaiting paperwork for that - when the guard made the discovery, the spokesman added.
Rodriguez-Perez was then taken for booking on two counts of carrying of a loaded firearm without a license, and possessing a firearm or ammunition without an FID Card.
Boston Police had arrested Rodriguez-Perez last July on charges he broke into two South End residential units - fleeing with four laptops and other items. He pleaded guilty in August and was sentenced to two years of probation, according to the Suffolk County District Attorney's office.
