MILWAUKEE, Wisconsin, Nov 29 (Reuters) - An armed student took a class of high school students hostage on Monday in the town of Marinette, Wisconsin, and the standoff was continuing, an official of the county emergency management office said.
Police were dispatched to the Marinette High School after a call at 3:48 p.m. local time, the official said.
At a hair salon across the street from the high school, a woman identifying herself as Tracy told Reuters by telephone that the school was surrounded by police cars and fire trucks and the parking lot nearby was filled with people, many of them students.
No injuries have been reported. The high school has about 800 students, according to its web site.
Marinette is about 50 miles north of Green Bay, Wisconsin.
