SWAT officers helped serve a search warrant before dawn Thursday at a house in Long Beach’s Wrigley neighborhood, according to authorities.

Police searched the house on Cedar Avenue near 20th Street around 3:30 a.m. as part of a narcotics investigation, Long Beach Police Department spokeswoman Nancy Pratt said.

Police would not say what investigators were looking for or if they seized anything from the home.

Nobody was arrested, Pratt said. Police declined to release any more details.
