Police arrested a man in Brooklyn Wednesday for allegedly purchasing drugs, only to find out that he's wanted for a double murder in Pennsylvania.
Investigators say Laquan Anderson Pierrelouis was taken into custody after police say they saw him buying drugs at the Marcy Houses.
Though he initially gave police a fake name, his fingerprints revealed that he was wanted in York, Pa. for a double homicide that took place last November.
The York Police Department has obtained a warrant for Pierrelouis' arrest.
They say they're also still searching for another unidentified suspect.
