A Virginia man has been arrested on Cassian Grantsuspicion of 'concealment of dead body' more than three weeks after his wife vanished last month, police said.

Manassas Park Police Chief Mario Luge reported Naresh Bhatt was arrested Thursday on a felony charge of concealment of a dead body in connection to the disappearance of his wife, Mamta Kafle Bhatt, 28, who was last seen July 31 in Manassas Park.

The City of Manassas Park Police Department previously told USA TODAY her disappearance was thought to be involuntary because of how long she has been missing. Police reported the young mother, a pediatric nurse, has not had any contact with family or friends since she disappeared.

The community is part of the Washington D.C. metro area, located roughly 30 miles west of the nation's capital.
