A Muslim woman wearing religious attire was set on fire in New York City on Saturday night, just hours before the anniversary of the Sept. 11, 2001 terrorist attacks.

The woman, a Scottish tourist shopping on Fifth Avenue, noticed her sleeve was on fire and quickly put it out, the New York Daily News reported.

“She saw (the suspect) pull a lighter away and walk away,” a police source told the newspaper. “He doesn’t say anything.”

Police are investigating whether the incident may be considered a hate crime, and are searching for the suspect, Fusion reported. No description for the attacker was released to the public.

The victim is a 35-year-old dentist from Glasgow, according to DNA Info. She was not badly injured and refused medical attention.

“We will advocate for a full investigation,” the Council on America-Islamic Relations wrote on Facebook.

HuffPost has recorded more than 230 acts of anti-Muslim violence, discrimination and political speech in the United States this year. During the month of Ramadan, there were at least 20 anti-Muslim crimes.
