OTTAWA - Police are investigating after a man was seen committing an obscene act to the National War Memorial.

Officers say bystanders saw the man climb the statue and begin the lewd activity late Sunday night.

A 22-year-old man was arrested at the scene.

The tall granite cenotaph near Parliament Hill features a number of bronze statues and is meant to symbolize the sacrifice of Canadians who have gone to war.

Veteran's Affairs Minister Erin O'Toole issued a brief statement late Monday condemning the act.

"It is disheartening that some people cannot respect the sacredness of the National War Memorial," he said.
