One of the men had all black Middle Eastern dress like a tunic, black pajama bottoms and sandals and wanted to"cash a check"
The other, unknown type clothing description, was also Middle Eastern and "wanted to sell a laptop."
The first one was caught by the building's "man trap" entry when he piggy backed in with an employee on her credentials. He hesitated at the second door and was caught in the vestibule. The employees have to badge in and badge out.
