Police are seeking the public's help in identifying a man who allegedly walked out of a Barrie, Ont., Walmart with a shopping cart loaded with meat.

Police say a security guard arrested the man on Tuesday evening after he allegedly walked past the cashier and left the store with the filled cart.

But investigators say the man got away, fled across nearby Highway 400 and the security guard lost sight of him.

The cart, containing more than $1,200 worth of meat and other grocery items, was recovered.

The suspect is described as white with a tanned complexion, approximately 5-feet-11-inches and 200 pounds.
