The first robbery took place at the Chase Bank ATM on Hobson Road at Naper Boulevard at about 9 p.m. A man with a gun jumped in front of a car as it began to drive and motioned for it to stop.
The robber then entered the vehicle through the rear driver's side door and demanded money. He then fled the scene on foot. Police said the male suspect was wearing all dark clothing.
The second robbery took place about an hour later on the 3300-block of South Route 59. A pizza delivery driver was robbed by a man with a handgun.
The suspect fled the scene on foot to a sedan. That suspect is described as a white male, 6 feet tall, thin build and wearing dark clothing.
