The LAPD has opened a criminal investigation into allegations the Metropolitan Medical Center dumped patients on Skid Row. Police say they videotaped ambulances from the hospital dropping off five patients in front of the Volunteers of America homeless services center on Sunday. The head of the medical center, located near Western and Adams, denies the allegation. He says three of the five gave Skid Row addresses on their admission information. Captain Andrew Smith heads the LAPD's Central Division. He spoke with KPCC's Frank Stoltze about the investigation.
