FREDERICK, Md. -- Police said they are investigating a possible hate crime in Frederick County after vandals defaced a mosque last week.
Authorities said someone threw large stones through some of the mosque's windows last Wednesday.
The incident is the third of its kind against the Islamic Society of Frederick in just more than a year, officials said.
A window was broken at the mosque three weeks ago, News4's Keith Garvin reported.
"It does tell us that this society is sensitive to the probability that they could be being targeted. As an agency, we are very sensitive to that," said Lt. Tom Chase of the Frederick City Police Department.
Despite the recent incidents, the leaders at the Islamic Society of Frederick said they are not ready to categorize them as hate crimes.
