(Adds that lockdown was lifted, similarity of threat to Oregon
shooting)
TORONTO, Oct 16 (Reuters) - A lockdown at Canada's Wilfrid
Laurier University in Waterloo, Ontario was lifted Friday as
officials determined that an Internet threat, similar to one
made ahead of a recent shooting in Oregon, was not credible,
university and local police said.
The lockdown ended less than six hours after it was imposed
early Friday and no arrests were made, they said.
Waterloo police said they were still attempting to locate
the individual or individuals who posted the threat online on
4chan.org, an image-based bulletin board, and added there was a
possibility the person or persons responsible for the post were
not local.
They said the threat was directed at a science building at
the campus, but further details weren't immediately known.
The threat was similar to an anonymous online post on Oct. 1
on 4chan.org, hours before a 20-year-old gunman opened fire at
Umpqua Community College in Roseburg, Oregon, killing eight
people, police said.
"We are still making efforts to determine the exact location
of the poster. There is indication right now that the poster is
not local," Waterloo Regional Police Superintendent Pat Deitrich
told a news conference.
Waterloo, home to two universities, is located about 113
kilometers (70 miles) west of Toronto.
