SUN VALLEY – Five men accused in a home-invasion robbery were being sought today in connection with ransacking a home, tying up a family and stealing their car. At least one of the men was posing as an officer and all five were dressed in business attire at the time of the robbery that occurred 8:30 a.m. Monday in the 8600 block of Sharp Avenue, police said. The drama began when the men pulled up to the house in a mid-80s Chevrolet van, and one man pulled a gun on a resident, took his wallet and ordered him to go to the back of the home, police said. The others, meanwhile, waited out front for their partner to open the front door, police said. Once inside, the intruders tied up a man, his sister and two children, aged 10 and 12, police said. A 3-year-old was also in the home. At one point, a gunman put a pistol to the head of one victim and told him or her: “Don’t look at me. I’m an undercover police officer,” he said. The robbers ransacked the place, taking items such as a plasma TV, a microwave and an unspecified amount of cash. The men were described as Latino, 40-50 years-old. Their vehicle was described as a brown 84-85 Chevy full size van. The van has two 10-inch orange stripes on the side on both sides and it has a rear ladder. Police this morning were searching for two vehicles: the stolen black 1996 four-door Maxima bearing California license plate 4RIF738, and the getaway van, which has faded gray or brown paint, a 10-inch orange stripe, and a rear ladder. Anyone with information was urged to call the North Hollywood Station at (818) 623-4018.
