An estimated 40,000 revelers crowded onto Franklin Street on Saturday night for Halloween, according to Chapel Hill Police.

Orange County Emergency Services responded to 10 calls within the closed event, according to officials. The majority of EMS calls were alcohol related.

There were no arrests made or citations issued in the closed area, according to Chapel Hill Police.

The streets were cleared at 11 o’clock Saturday night and opened to traffic just before midnight, after being cleaned by Town crews.

While no arrests were made at the Homegrown Halloween event, an Alert Carolina message went out early Sunday morning warning students that campus police were investigating a report of a sexual assault just before three o’clock Sunday morning.

Campus police say the assault reportedly occurred in UNC’s Hinton-James Residence Hall.

A male suspect, estimated to be 6’ tall and weighing between 180 and 200 pounds, is believed to have left the campus area, according to police.

Anyone with information is asked to contact 911 or call Crimestoppers at (919) 942-7515. Calls to Crimestoppers are confidential and anonymous and the caller may be eligible for a cash reward for information that leads to an arrest.
