Naperville, Illinois police are looking for two women who they suspect attacked a Chinese man while he was out jogging. According to the Chicago Sun Times, police released pictures of the suspects in the hopes of identifying the women. They are offering up to a $1000 reward for any information that leads to the suspects’ arrest.

The incident occurred on March 21 around 3:45 pm near 75th and Washington streets. According to WBEZ, a 60-year-old Chinese man was jogging on the trail when the two suspects allegedly assaulted him.

According to the victim’s 31-year-old daughter, who wished to stay anonymous, one of the suspects threw a log at him before telling him he was sick and that he should “go back to China.” After, the suspect spat on the victim, according to the daughter.

The daughter said her father is “doing fine physically, but emotionally, he is more scared that a similar thing will happen to me and my brothers.”

She and her Korean husband are both doctors in New York City and are on the front lines of treating coronavirus patients. But this incident has left her with more stress during these already stressful times.

“It’s definitely an extra layer of stress,” she said of having to deal with patients and worrying about her parents. “Naperville is considered pretty safe. If anything, my parents were telling me and [my husband] to be careful in New York City.”
