30,000 turn out for Chapel Hill's 'Homegrown Halloween'

Fifteen people were treated by Orange County emergency personnel for alcohol-related issues, and seven of them were taken to UNC Hospitals for continued evaluation, officials said. No arrests were made during the sixth annual "Homegrown Halloween."

Streets in the area of Franklin Street were cleared by 11:45 p.m., and the area was reopened to traffic at about 12:45 a.m. 

In previous years, the Halloween celebration attracted enormous – and sometimes unruly – crowds.

In 2007, there were approximately 82,000 people – more than the town's population of 54,000 – which caused public safety concerns downtown, on the University of North Carolina at Chapel Hill campus and in nearby neighborhoods.

An estimated 22,000 people attended the 2012 festivities.
