FAIRFIELD — Two incidents of a man passing fake $100 bills were reported to police on the same day last week.

The first report was received around 2 p.m. April 20 from the owner of Dairy Queen, 1902 Post Road, who said his cashier was given a counterfeit bill from a man to purchase a cup of iced coffee. The cashier said the suspect kept looking over his shoulder at a car, with two other men sitting inside. She said she thought the bill might be fake, but felt intimidated. According to the report, the bill already had marker checks on it, indicating it was fake. Surveillance video of the incident is being reviewed.

Around 4:15 p.m., employees at Pinkberry, 1512 Post Road, called police to report that a man had paid for $3.70 worth of frozen yogurt about two hours earlier. The suspect was described as about 5 feet, 9 inches tall, wearing a black shirt with a yellow Nike logo, black gym shorts and a black cap with a yellow Nike logo.
