Story highlights At least one person, a subcontractor, has been disciplined so far

Facebook slams the content, says it removes posts promoting "sexual violence or exploitation"

(CNN) US Marine Corps officers on Monday huddled on how to proceed with tackling a new and shocking scandal: the online posting of potentially hundreds of explicit photos of current and former female Marines and other service members on a private Facebook page.

So far, at least one person has been disciplined in connection with the postings, a US military official said. He was an IT subcontractor working for a firm with a support contract for the Marines.

The Marines informed the primary contractor of the person's actions and he has been barred from working on any contracts in support of Marines, the official said. The man committed "misdeeds," the official said, but there were no details about precisely what he did.

The Naval Criminal Investigative Service kicked off an in-depth investigation into the postings of the salacious and explicit photos on the Facebook group called Marines United.
