Prince George’s County police said Osman Kalokoh was arrested Tuesday morning in Baltimore.

Detectives learned that 2:50 a.m. Tuesday that a man drove himself to MedStar Good Samaritan Hospital in Baltimore on a golf cart.

The man initially refused to provide any information on his identity, but a Baltimore police officer determined it was Kalokoh and he was wanted in Prince George’s County for homicide. The officer took him into custody.
