A Garden City, Michigan, man is accused of making threats to people attending a march for justice event Saturday in Dearborn. 

Anthony Young, 27, was arraigned Monday on one misdemeanor count of malicious use of telecommunication services.

Dearborn police say Young was arrested "within hours" after he allegedly made threats to harm those attending the annual Arbaeen procession on Saturday. Dearborn-based nonprofit Karbalaa Islamic Educational Center said the event honored Imam Hussain, a prominent figure in Islam.

Police say they learned of the threats allegedly made by Young as part of the department's online monitoring operations.

Dearborn Police Chief Issa Shahin and Dearborn Mayor Abdullah Hammoud issued the following joint statement on Saturday in response to Young's alleged threats:

"When someone threatens violence against our community, we will act swiftly and decisively. There is zero tolerance for threats of this nature, and anyone who attempts to sow fear or division will be held fully accountable. The safety and unity of our community will always come first."

Young was given a $5,000 bond and ordered to wear a GPS tether, police said. 

"Dearborn Police ensures safety and security at the many cherished community events that occur in our city both by our presence, planning, and preparedness, but also by vigilantly monitoring online spaces for threats made against citizens. We will always pursue arrests and accountability from individuals in such cases," said Dearborn Police Chief Issa Shahin in a statement. 

The Shia Muslim Foundation, a nonprofit supporting the civic rights of American Shia Muslims, says it's "deeply alarmed" by the alleged threats.
