In D.C.:

An 86-year-old D.C. man got a surprise visit earlier this month. Robert Smith heard someone banging on his apartment door on Randolph Street on the evening of March 4. But before he could unlock it, a group of D.C. Police officers battered the door down and knocked Smith onto the floor.

Smith said officers quickly realized they had the wrong apartment and called for an ambulance. Doctors treated Smith for contusions to his head and back.

"There's a half million people in this city, so why did they have to pick on me?" Smith told FOX 5.

The retired federal government worker has lived alone in the same apartment for more than 30 years and said police never offered an apology for the mistaken raid.

FOX 5 viewed the search warrant which stated police were looking for marijuana, drug paraphernalia and anything related to drug trafficking.

The Director of Communications for the Metropolitan Police Department, Gwendolyn Crump, e-mailed FOX 5 saying that "The Metropolitan Police Department is investigating this matter."
