BOISE, Idaho (AP) — Authorities are investigating after Boise's newly dedicated memorial honoring Vietnam War veterans was vandalized.

Police were at Veterans Memorial Park on Sunday after six medallions were removed from the granite memorial. The medallions had represented the five branches of the military and the Vietnam Veterans of America. The president of the group's Treasure Valley chapter, J.D. Poss, estimated the damage at more than $3,300.

Hundreds of people had attended the memorial's dedication ceremony on May 30. The monument includes the names of 217 Idaho residents who died in Vietnam between 1961 and 1975.
