Naomi King, the Rev. Martin Luther King Jr.'s sister-in-law, was attacked in a carjacking attempt outside her retirement home in Atlanta, according to police.

King, who is in her 80s, told investigators that she was driving into the front entrance of Big Bethel Village retirement community Friday when two people came up to her car and one told her to get out, police said. When King refused, one of the suspects hit her in the mouth, they said.

Atlanta police said King, the widow of King's younger brother, A.D. King, suffered minor injuries. A post on the website of her late brother's foundationsaid Saturday that she had been released from the hospital.

King and her husband were also significantly involved in the civil rights movement.

The great grandmother told NBC station WXIA that she "wasn't scared" during the assault because she has faith on her side. When the assailants fled, King said, she "said a quick prayer and thanked God that my injuries was at a minimum."

The A.D. King Foundation's post said King and other residents are urging National Church Residency, which owns Big Bethel Village, to increase security in light of the attack. National Church Residency did not immediately respond to a request for comment.

Atlanta police said that the suspects fled the scene and that the attack is under investigation.
