GILLETTE (WNE) — Police are investigating after an unknown man called Walgreens threatening to shoot up the store if it didn’t meet his demands.

Walgreens staff received a call at about 1:30 p.m. Sunday from an unknown man asking for $3,000 in Apple gift cards for his children’s health care, said Police Deputy Chief Brent Wasson.

Wasson said the man threatened to “enter the business and shoot people” if his demands weren’t met.

Four police officers responded to the store and quickly determined there was no immediate danger, Wasson said. 

Police called the phone number that the man called from, but it was out of service or had been disconnected.

Wasson said Monday morning that there is no danger to the public, and the investigation continues.
