Winslow Township High School was locked down and students confined to their classrooms yesterday while authorities investigated reports that a gunman was inside.

The incident lasted for several hours during a search of the Camden County school, said Bill Shralow, a spokesman for the county Prosecutor's Office.

No weapon or suspect was located, but the investigation will continue. "It hasn't been disproved," Shralow said. "They're obviously not going to drop the whole matter."

No threats were made, he added.

The school, which has nearly 1,700 students in grades 9 through 12, was the target of a foiled gun-and-terror plot last year. The district has been plagued recently with violence and threats that have interrupted classes. - Inquirer staff
