Thirty-six officers suffered minor injuries from flying rocks and bricks in the hours following the death of 20-year-old Brandon Webber, who was killed Wednesday evening after he exited the vehicle holding some type of weapon, authorities said.
Sawyer tweeted that she went to the Frayser neighborhood because 'this is my district.
He said at a news conference on Thursday morning that in the course of the unrest he was impressed by law enforcement officers' "professionalism and incredible restraint as they endured concrete rocks being thrown at them and people spitting at them".
"While attempting to stop the individual, he reportedly rammed his vehicle into the officers' vehicles multiple times before exiting with a weapon", the bureau asserted in a statement.
After Webber was shot as marshals were trying to arrest him Wednesday evening, Strickland said, protesters threw rocks and spit on police, injuring officers who responded.
Two journalists were injured and six police officers were hospitalized in the clashes late Wednesday, according to Memphis Mayor Jim Strickland. Activists associated with the Black Lives Matter movement also have sued the police department, claiming officers illegally surveilled them.
Authorities in Tennessee are investigating a shooting involving members of a regional fugitive task force.
But the fatal shooting touched off outrage in Frayser, a predominantly black area in northern Memphis. TBI investigators then give their report to the district attorney, who will decide whether to pursue charges against officers involved.
Marshals then opened fire, killing the man, she said. Mounted police, a helicopter and tear gas were all required to disperse the crowd. It is, as yet, unknown how many shots were fired or how many times the suspect was hit.
"Let me be clear - the aggression shown towards our officers and deputies tonight was unwarranted,"Memphis Mayor Jim Strickland, D, said".
In the aftermath of clashes between police and protesters, the district attorney for DeSoto County, Mississippi, where Webber was suspected of shooting a man to steal his auto, on Thursday afternoon defended the actions of the federal marshals.
"As news of his death spread, protestors destroyed a concrete wall outside a business and smashed the windows of squad cars and a fire station".
"This remains an active and ongoing investigation, as TBI special agents and forensic scientists continue to work to gather any and all relevant interviews and evidence", agency officials said.
Police director Michael Rallings implored residents to wait until the TBI finishes its investigation before spreading possible misinformation about the shooting.
Passion Anderson, a 34-year-old student, drove her 13-year-old son to the scene early Thursday, after protesters had gone and the scene had calmed down.
Webber's home is in a residential area of the working-class neighborhood of north Memphis.
'I just want him to see this, know what's going on, to be conscious, ' she said. "I fear for him all the time".
