The Metropolitan Police Department said it is investigating the offense as "potentially being motivated in whole or in part by hate or bias."
The store owner, Chonghu Lu, told police a man walked into Max Trading on 4th Street NE and asked to open a package to look at the merchandise, according to a police incident report.
When Lu said no, the man began punching him in the face and made a racist statement before leaving the store, the report said. The surveillance video, provided to CNN by the store, shows the man punching Lu in the face, knocking him down and continuing to punch him.
"He beat him, punch him, he fell on the floor, and beat him," the wife of the store owner, Cong Cong Lu told CNN on the phone.
Lu said she tried to help her husband and stop the attack, but the man got away. She can be seen on the surveillance video putting herself between her husband and the man punching him, trying to protect her husband.
Lu said her husband had to get 14 stitches following the attack but is doing better.
When asked if she was worried about reopening the store even though the suspect hasn't been caught, she replied, "We had to open the store. We have to make a living, had no choice."
Police are also looking for a woman who they call a person of interest that was with the suspect at the time of the attack. In the surveillance video, the woman is seen trying to pull the man off the store owner as he punched him repeatedly.
