An off-duty Melrose Park police officer was in custody after a fatal shooting Tuesday in west suburban Maywood.

Two men were shot about 7:30 p.m. in the 400 block of West Lake Street, according to a statement from Maywood police.

The off-duty officer was involved in the shooting, according to a spokesman for the village. The officer has been placed on paid administrative leave while the investigation is ongoing.
