Norway ? Six people were indicted Monday for their alleged roles in the brazen daylight theft of the still-missing Edvard Munch masterpieces “The Scream” and “Madonna,” a prosecutor said.

Masked gunmen grabbed the versions of two of Munch’s best-known works from the Munch Museum in Oslo in August 2004, as stunned visitors looked on.

State attorney Oslo Terje Nyboe said five of the six people indicted Monday will be tried for participating in the theft, while the sixth was indicted on charges of receiving stolen goods. Police said he briefly stored the artwork before it was moved elsewhere.

None of the six was identified, in line with Norwegian practice regarding privacy.

Despite an international search and the promise of a $300,000 reward by the City of Oslo, which owns the museum, the works have yet to be recovered.
