Police are looking for a woman accused of attacking a pregnant Asian-American woman and her daughter last week in Philadelphia.

Jing Chen was walking along 13th and Walnut Streets when a woman allegedly crossed the road and started spraying water at her and her child. "What made you do that?" Chen said to the woman.

"She turned around and tell me 'because you are fu**ing Chinese' and my daughter was right there and she said 'you too,'" Chen explained to ABC 6 News.

Police are searching for a woman believed to be a known local beggar in the area, but will not likely charge the suspect on the basis of ethnic intimidation.

"This is an active investigation and we have not ruled out additional charges, but there is not sufficient evidence that has been presented to us that this is a case of ethnic intimidation at this time," said the District Attorney's office in a statement.

"The assailant deliberately crossed the street and singled them out and then mentioned race during the attack," said Anna Perng, an advocate for immigrant communities and those with disabilities working with the Mayor's Office.

Instead the suspect may be charged with simple assault, harassment and recklessly endangering another person.

Chen has warned other families on social media channel WeChat about potential attacks on the Asian-American community.

"I haven't been out of the house until yesterday," said Chen. "It's made me feel so scared," continued the expecting mother.

Newsweek has contacted the Philadelphia Police Department and the Philadelphia District Attorney's Office for further comment.
