The channel will air ten new episodes later this year, The Telegraph reports. The second series, starring Sofie Grabol as detective Sarah Lund, has already been shown in Denmark.
Richard Klein, the controller of BBC Four, said: "The Killing is the most intensely thrilling televison drama experience in British broadcasting of the moment and I'm delighted that series two will be on BBC Four. It is a diamond of a series - complex, dramatic, thoroughly gripping.
"It never loses sight of its truly brilliant insight: the humanity and the emotion that goes on behind a police investigation into a brutal and sordid murder. At its heart, this is The Killing's genius - to truly portray the human cost of tragedy. And it is to the BBC's acquisition department that real credit lies for the clever discretionary spot-and-pick-up of a gem of a series."
Sue Deeks, head of programme acquisition for the BBC, added: "BBC Four viewers have been utterly gripped by The Killing and we are delighted to announce that they will be able to enjoy the next compelling series later this year."
