OCEAN BEACH — Police officials swarmed a home in the 2900 block of Chatsworth Avenue after six armed men forced their way into a nearby residence on Santa Cruz Avenue near Cable Street on Dec. 16, robbing the home’s occupants of cell phones, a laptop computer, a safe and marijuana, according to authorities. Two men were arrested outside the Chatsworth Avenue home and four others were detained for questioning, police said. The incident unfolded shortly after 2 a.m. when the suspects forced their way into the back door of the Santa Cruz Avenue home wielding handguns and expandable batons. From witness accounts, officers descended on the second home, where a police helicopter overhead spotted two suspects trying to flee. Investigators said no one was injured in the initial home-invasion robbery, and police and sheriff’s officials are searching for a link between the case and another home break-in four hours earlier in Rancho San Diego. — Kevin McKay
