DICKINSON (AP) - A 16-year-old boy has been charged in juvenile court with felony terrorizing, after he allegedly made threats that prompted a lockdown at a high school here, authorities say.

Police Capt. Stewart Stenberg said the boy remained in custody on Tuesday, a day after he allegedly made the threats. The boy's name has not been released because of his age.

Dickinson High School Principal Ron Dockter said he plans to meet with students over the next few days and discuss the lockdown and emergency procedures.

Authorities said the lockdown was ordered Monday morning after they got a report of "unspecific" threats by a student. It was in effect for about an hour, until the 16-year-old was taken into custody near his home for questioning.

"In this situation, we like to be pro-active so we went into lockdown, which went very well with the police department, students and staff," Dockter said. "We never had a threat in the building."

Students and faculty members remained in their classrooms. During a lockdown, no one is to be in the hallways or bathrooms, windows and doors are closed, blinds are drawn and everyone is asked to remain quiet, Dockter said. Law enforcement officers were at the school entrances, and Dockter said he made an announcement to students.

"I got on the public announcement system and told everyone we were in lockdown mode for an alleged threat. Lockdown lasted from about 8:15 to 9 a.m," Dockter said.

Senior Kayla Fuchs was in choir class at the time.

"Our teacher locked the doors and we kept singing," Fuchs said. "Our teacher came around my class and said what he could, but while we were sitting there we had no idea what was going on. We were like 'OK, is someone in the school?"'

Others said they were not sure what was happening.

"I thought it was a drill," senior Jerad Binstock said. "I wasn't scared about anything, I wasn't aware of what was going on right away."

After the incident, the school is reviewing its emergency procedures.

"There aren't any drastic changes, just things like who locks a certain door or gate," Dockter said.

"These kinds of things are not unique to Dickinson unfortunately," Superintendent Paul Stremick said. "It can happen anywhere, but keeping students safe is No. 1. We are definitely more cautious now, not just because of recent developments here and elsewhere in the last month, but in the last few years."
