T.G.I. Friday said a severed snake head found in a dish of broccoli at one of its upstate New York restaurants was likely planted in the meal.

The Carrollton, Texas, company says Friday it  asked the New York State Police to open a criminal investigation into product tampering. Spokeswoman Amy Freshwater said the snakehead was sent for testing at an independent laboratory that confirmed it had never been cooked and was added to the cooked broccoli.
