Riverside Secondary was locked down for about an hour Thursday afternoon for an incident involving a student from another school district.

Coquitlam RCMP Cpl. Jamie Chung said he couldn't disclose much information because of the age of the people involved in the situation at the Port Coquitlam school. However, he said the lockdown was triggered by something the student from another district said to a Riverside student.

"It was serious enough to warrant the degree of police response," Chung said.

"In the end, I'm glad that nobody was hurt and it ended without incident and it didn't take a long time to end."

The student from another district was taken into police custody for investigation.

"It is for investigation of something serious that we feel may be a danger to the public if we didn't take such a measure," Chung said, adding that, "We take this type of incident very seriously and that's why we err on the side of caution and have a lockdown at the school to protect the safety of the student," he said.

As students Tweeted about the lockdown, parents called the school to find out what was happening. A secretary who answered the phone Thursday said the situation had been resolved, but many people were calling to request information.
