HARTLEY TOWNSHIP, Pa. -- Fire crews were called to a bar and restaurant near Hartleton Friday afternoon.
According to officials, the fire broke out at Boomerang's Bar & Grille along Old Turnpike Road just after 3 p.m.
Customers and staff were inside at the time but everyone made it out safely.
The restaurant is a total loss.
Crews tell Newswatch 16 they had a hard time getting a handle on the flames because the section of the building is old and had several layers.
Authorities say they are not sure how the flames sparked but a state police fire marshal has been called in to investigate the cause of the fire in Union County.
