An elaborate hoax in New Hope, Pennsylvania, caused streets and businesses to close for several hours Sunday night, police said.
Officials investigated reports of a possible shooting and barricade situation near Ferry Street, only to later learn an anonymous call to 911 was actually a prank.
Several residents told NBC10 that they received calls from police to shelter in place.
The Bucks County District Attorney's Office said the fake emergency call was made around 5 p.m. and that authorities from multiple jurisdictions responded. The all clear was given around 9 p.m.
Authorities are now working to track down the caller. It is illegal to knowingly raise a false alarm in Pennsylvania and doers can face a misdemeanor charge under state law.
