WEST ALLIS, Wis. -- Wisconsin State Fair officials say more officers and new rules helped keep things calm, a day after dozens of youths fought inside and outside of the grounds.
At least 31 people were arrested and at least 11 people were injured on opening night Thursday.
Fights erupted around 7 p.m. in the Midway area and spread into neighboring streets around closing time.
New rules were implemented Friday that require all people under 18 to be accompanied by a parent or legal guardian in order to be admitted to the grounds after 5 p.m.
Gov. Scott Walker also ordered the State Police to help keep order and Milwaukee Police Chief Edward Flynn promised additional officers.
Fair spokeswoman Patrice Harris tells the Milwaukee Journal Sentinel that Friday evening was violence free.
