Historical police drama Copper has walked its last beat after producers announced the show has been scrapped after two seasons.

The series, starring Tom Weston-Jones as an Irish immigrant policeman in 1860s New York, won acclaim upon its debut last August (12), but bosses at BBC America have decided against a third season.

The season two finale and final episode will air in America on Sunday (22Sep13).

BBC America General Manager Perry Simon says, "The opportunity to work with... the extraordinary cast and crew on this journey is one that we are extremely proud of. Their vision to re-tell the immigrant experience through the melting pot of New York City was an original and fresh idea.

"After 23 episodes, with (President) Lincoln dead and the nation starting to heal, it seems a fitting moment to conclude this American story."
