Campus and city police officials said Halloween brought about weird crimes as people enjoyed the holiday.
Director of Public Safety Gene Burton said Ball State University Police made 12 arrests on Saturday, and some people were issued more than one citation.
He said they made about as many arrests as in years past.
"We see more activity [during Halloween weekend] than other weekends in the fall," Burton said. "It's more of a party holiday. People get wrapped up more than normal."
Burton said the department has not yet considered how to address this increase in the future.
Muncie Police Captain Chuck Hensley said he was surprised that less arrests were made by city police this year than in years past.
Muncie Police issued far fewer arrests than they did last year, but the exact number was not available as of 5 p.m. on Monday.
"It was more peaceful," Hensley said. "It was weird. It was just Mickey Mouse stuff, like shooting paintballs at trick-or-treaters."
He said the police department has downsized from a staff of 107 to 98 employees.
"We can't afford to have more officers out over Halloween," he said. "There were actually more arrests on Sunday. I'd say nearly 100 percent were on the southeast side of town, and they were domestics and weird things."
Hensley said 47 calls were made on Sunday morning, including reports of security alarms going off, gas station drive offs, fights, threats, traffic accidents, battery, auto burglary and juvenile problems.
"Traditionally it's nuts," Hensley said. "Last year, I took 16 calls [on Halloween], and 196 calls were made altogether."
