Update:

Less than six months after the owner of Mary's Fabulous Chicken and Fish was brutally beaten and robbed, police are investigating another armed robbery at the restaurant on Wednesday night.

Police were called about 6:40 p.m. Feb. 4 to 3220 Packard Road in Ann Arbor after a report that the restaurant owners, Yong and Doo Kim, were robbed at knifepoint.

Lt. Robert Pfannes said the robber entered the store, pushed the 75-year-old male owner to the ground and held the 68-year-old female owner at knifepoint.

The individual then took an undisclosed amount of money and fled on foot, Pfannes said.

No one was injured in the incident.

The robber is described as a heavy set, light-skinned black male, about 30 to 40 years old. He is about 5 feet 4 inches or 5 feet 5 inches tall with a mustache. He was last seen wearing a black sweatshirt and gray sweatpants.

The robbery follows an attack on owner Yong Kim as he was walking to his car on Aug. 26, 2014.

The two 16-year-old boys accused in the attack, Antonio Young and Carmichael Chavis, have pleaded guilty in the assault.

The two admitted to punching, kicking and beating Kim with a milk crate before taking his wallet in Washtenaw County Trial Court last week.

Kim suffered two large cuts on top of his head, requiring about 20 staples, and had extensive damage to his face and neck.

The two, who are charged as adults, pleaded guilty to charges of armed robbery, conspiracy to commit armed robbery and assault with intent to commit great bodily harm less than murder.

A charge of assault with intent to rob will be dismissed at their sentencing hearing, set for later in the month.

In a December interview, Yong Kim said despite still suffering from some injuries in the attack he is much better and ready to move on.

"I forgive them," he said in December of his attackers. "I'm not angry, just sad they learned to do bad things early. It's a society problem."
