A group of self-proclaimed Native Hawaiian Sovereignty advocates last night occupied Iolani Palace in Honolulu, the former home of the Hawaiian monarch.
State police arrested 22 members of the Kingdom of Hawaii, Nation at the palace.
The Honoluolu StarBulletin says an Iolani Palace official was reportedly injured by the occupying group.
The brief takeover, which included padlocking the gates and posting signs proclaiming the occupation, took place on Statehood Admission Day.
It is a state holiday marking the day in 1959 when Hawaii became the fiftieth state of the United States of America.
It was the second time this year a sovereignty group had locked the palace gates.
About 70 members of a separate group, the Hawaiian Kingdom Government, occupied the grounds on April 30th
