The oldest son of Martin Luther King Jr. tweeted Friday evening that he is “deeply disturbed” by the recently released videos that show the altercation between City of Memphis, Tennessee, police and Tyre Nichols.

“We all witnessed a horrific yet perversely familiar act committed by officers of the law,” Martin Luther King III tweeted.

He called for “everyone involved” to be arrested and charged with murder. Five police officers have been fired and face several charges, including second-degree murder and aggravated assault.
