The elderly Korean American man who was attacked inside his own store is speaking out.

A customer who refused to pay attacked Ki Tae Lee, 66, on Saturday inside his store in Brooklyn, ABC 7 New York reports. CeFaan Kim, a reporter for ABC 7 New York, posted video footage of the attack on Twitter.

In the video, the customer throws items off the store counter. Lee confronts the customer who begins punching Lee.

“He was saying some sort of curse words and derogatory things, but I can’t say exactly what they were,” Lee told ABC 7 New York.

It is not clear yet if this incident is a hate crime. Hate crimes against Asians have increased by 361 percent in New York City this past year, NBC News reports.

Lee says this isn’t the first time the store has been attacked. Last month, someone broke the store’s glass window and told the owners to go back to their country.
