Four men are facing home invasion charges after a break-in at a Brighton home in which an intruder held a knife to a teenager and demanded money and marijuana, the Suffolk district attorney’s office said. Peter Matthews, 18, of Brighton, and Anthony Gilbert, 19, of Allston, are expected to be arraigned Monday. Ricardo Delice, 18, of Brockton, and Leon McKoy, 19, of Dorchester, were ordered held on $100,000 bail at their arraignments in Brighton District Court on Friday, prosecutors said. The four men, accused of breaking into a home on Nottinghill Road about 2:30 a.m. on Nov. 24, were arrested Friday, authorities said. During the break-in, a teenager woke up and saw the intruders. After the men demanded money and marijuana, they asked who else was home. When the teenager said his parents, the men decided to leave, authorities said.
