A bar manager in Canada is hoping to nail the culprit who stole a mummified toe used in their signature cocktail.

The Downtown hotel in Dawson City, Yukon, offers a unique drink called the Sourtoe Cocktail. Any drink can be used in the concoction, but the special ingredient is a a shrivelled black human toe.

Those who touch the gnarled digit with their lips as they drink are awarded a certificate.

One customer tried the signature drink on Saturday, swallowing the drink before making off with the toe.

"We are furious," Terry Lee, the hotel's Toe Captain, said in a statement.
