UPDATE: A toddler was found unharmed in the District Heights area after an Amber Alert was issued for him Monday night, Prince George’s County police said.

A county police spokesman said in a Twitter message early Tuesday that Cesar Steven Martinez, who is about one year old, had been located.

Earlier Maryland State Police issued the alert for the boy who they said had been abducted in Prince George’s.

County police said the matter apparently involved a parental abduction which occurred Monday in the 7000 block of Nimitz Drive in District Heights.
