Federal law agencies are investigating whether an Oglala Sioux police officer improperly used a Taser on a man who was lying on the ground.
Tribal Public Safety Chief Ron Duke said that the officer probably used the stun gun on the drunk man between five and 10 times, trying to get him "to wake up and stand up."
The incident happened Friday afternoon in Manderson. Duke said the man was checked at a hospital and determined to be OK.
Duke said the officer is on paid leave while the FBI and the Bureau of Indian Affairs investigate the use of force.
The Associated Press was unable to immediately find a telephone number for the officer or determine if the officer had an attorney.
