Attention Walmart Shoppers.

McALLEN - Police and federal authorities are investigating the sale of six Bengal tiger cubs in a Wal-Mart parking lot Sunday afternoon.

The animals appear to have been bound for Mexico and neither the buyer nor seller had the permits needed to legally transport the endangered species across national borders, a federal agent said.

A group from Spring Hill Wildlife Ranch in Bryan was selling the cubs - four white ones and two orange ones - in the parking lot of the Wal-Mart near Jackson Avenue and Expressway 83.
