Government officers removed the protestors

Explanation:

In 1969 89 Native Americans occupied Alcatraz Island for 19 months, they wanted to claim the island as theirs because of the Treaty of Fort Laramie signed between the US and the Sioux in 1868. The Treaty said that that all retired, abandoned and out of use federal lands would be returned to the Native Americans.

The Occupation only ended when the government officers removed the protestors when they already cut all electrical power and freshwater from the protestors.
