About 1,500 people partied in the Ashland Plaza on Halloween night, but the unsanctioned event yielded fewer arrests than last year and no major incidents, police said.

Police arrested about a dozen people downtown on Sunday night, mainly for alcohol- and marijuana-related offenses, according to preliminary reports.

Last year, when Halloween fell on a Saturday, police arrested 29 people, largely for similar offenses. In 2008, police made 37 arrests on Halloween.

This year, between about 10 p.m. Sunday and 1 a.m. Monday, police arrested two people for driving under the influence of intoxicants, one for having an open container of alcohol in public, one for furnishing alcohol to minors and two for possessing less than an ounce of marijuana. Police also arrested four minors for being in possession of alcohol.

One man who was wearing brass knuckles was arrested for unlawfully possessing a weapon. Police also confiscated a firearm on Halloween night.

Police took four Halloween revelers to jail. A boy was lodged at the Jackson County Juvenile Detention Center for attempting to deliver marijuana. Three adults were lodged at the Jackson County Jail: two for probation violations and one for failing to appear in court on a misdemeanor charge.

There were no major problems at Sunday afternoon's Children's Halloween Parade, police said. A few children were reported lost but were eventually reunited with their parents, said Sgt. Bob Smith with the Ashland Police Department.

Police estimate 6,000 people attended the parade.
