An armed robbery investigation is underway this morning in Carbondale.

Police say two armed men wearing Halloween masks walked up to an employee outside a business in the 600 block of East Main Street last night, robbed him and then demanded the employee take them inside.

But as they came to the front of the business, the men ran off, police said.

It happened about 10 o’clock last night.
