Memphis police investigating more officers in Tyre Nichols case

The big picture: The Memphis Police Department relieved from duty the first seven officers the day after Nichols was beaten and hospitalized.

• Five of these officers were later charged with second degree murder.

What they're saying: "The administrative investigation is still ongoing, and so this information is subject to change," Sink said in an emailed statement.

• "The administrative investigation is solely to determine if City policies were violated and what disciplinary action should be taken," added Sink, who noted that the Tennessee Peace Officer Standards and Training Commission and the district attorney were overseeing the criminal investigation.

Of note: Police spokesperson Karen Rudolph said Tuesday an additional six officers "whose involvement has not been publicly disclosed could face administrative charges," according to AP.

• The Memphis Police Department declined to comment further on the numbers provided by Sink and Rudolph.
