More: Amber Alert issued for 4 Los Angeles-area children
Authorities said they issued a statewide Amber Alert early Saturday after Enrique Felix and Rose Chairez, both 28, allegedly kidnapped their four children -- 5-year-old Justin Felix, 7-year-old Enrique Felix, and 1-year-old twin girls Veronica Felix and Janeth Felix.
Police said the children were in protective custody with their grandmother because their father was physically abusive.
Los Angeles Police Officer Sally Madera said that while detectives are actively working the case, "as of right now, unfortunately, there have been no leads." She encouraged the public to contact police with any tips.
Police said the suspects fled in a dark-colored PT Cruiser with paper license plates and a missing right-rear hubcap.
Anyone with information is asked to contact the Los Angeles Police Department at (323) 342-4101.
