Students have now been released from a West Vancouver high school after being locked down because of a gun scare for more than three hours this afternoon.

West Vancouver Police ordered Rockridge High School to be locked down just after 1 p.m. Wednesday after responding to calls that one or two people were seen near the school with a firearm.

A full Emergency Response Tactical team, as well as members of the West Vancouver Police department and the RCMP, converged on the school just after the lunch hour.

West Vancouver School Superintendent Geoff Jopson confirms all students and staff are safe at this time.

Several students inside the school told CTV News they heard two people entered the school with what looked like guns.

But a room-to-room sweep of the school by police found no suspects, and police say there were no reports of shots fired.

Jopson says the school has practiced for this type of scenario in the past, and were well prepared for Wednesday's scare.

Around 840 grade eight to 12 students attend the high school, which is located directly across from Caufeild Village Mall on Headland Dr. in West Vancouver. Rockridge includes families from the areas of Bowen Island, West Bay, Caufeild, Gleneagles and Lions Bay.
