A woman who said she had a gun demanded a powerful painkiller from a pharmacy Friday but was arrested shortly after running off with the drugs, Suffolk police said.
She told an employee at Islip Pharmacy on Main Street that she had a gun and wanted OxyContin, an addictive painkiller, police said. The robbery happened about 2:20 p.m., police said.
But a short time later, officers arrested the woman in her car on Union Boulevard and Champlin Avenue in East Islip, police said.
No gun was found at the time, police said.
Police on Friday night declined to release her name and charges.
