German prosecutors say they are investigating a former Nazi concentration camp guard in the Berlin area on suspicion of murder after receiving a tip from the Simon Wiesenthal Center.

Spokesman Martin Steltner said Friday that the 87-year-old is alleged to have been involved in killings while serving as a guard at the Dachau camp near Munich.

The Wiesenthal Center's top Nazi hunter Efraim Zuroff said information on the suspect, identified only as Horst P., came in after the organization launched a poster campaign in July soliciting tips.

Germany's Bild newspaper published an interview with the suspect Friday in which he is quoted as denying involvement in any killings, but acknowledging that he did report prisoners for infractions who were then picked up and he "never saw them again."
