RCMP searched the Olympic village in Whistler with a canine team earlier this week after a suspicious map of the complex was found in the resort town.

Staff Sgt. Steve LeClair said the force was contacted Thursday night about the discovery of a map that appeared to be of the athletes village.

"There were unspecified notations on the map which gave cause for concern. Areas within the athletes village were searched extensively with a dog team," an RCMP statement said.

RCMP said nothing of note was found and the venue is secure.

They said measures have been taken to ensure the safety of the athletes and the public, and the investigation continues.

"There were some notations on it, I can't reveal the nature of them, that caused us some concern and out of an abundance of caution we ensured that the venue was searched thoroughly using police dog services, and upon completion of that we were satisfied that there was no danger or threat to any athletes or people in the venue," LeClair told The Canadian Press.

He said investigators were still trying to determine the origin of the map, which was found by a member of the public somewhere within Whistler village.

LeClair said no further security measures have been added. "No, the venue is secure. We have no reason to believe it has been compromised," he said, adding that he could not release details.

Follow-up investigation

Const. Carol Blannin, spokeswoman for the Integrated Security Unit responsible for Games security, said the Whistler detachment is heading up the follow-up investigation.

"ISU's involvement was to supply the manpower to do the security sweep of the venue," she said.

No threat was found, she said. "It's still the same security level — a low-threat."

Blannin said Vancouver Olympic organizers have been informed of the incident and will be updated on the investigation.

There are approximately 16,000 police officers and military personnel at the Olympics, including 6,000 police officers from 118 departments across the country.

There is a high level of security at Olympic Games, which have been targeted for terrorist attack before.

In 1972, a group of armed Palestinians raided the rooms of Israel's Olympic team in Munich, killed two athletes and took nine hostage. A failed rescue attempt by German police ended in the deaths of all of the Israelis in a wild shootout at a nearby military airfield.
