The personal data of roughly 400 Army employees at the Redstone Arsenal may have been compromised in a security breach.
The Army Material Command said Friday that a worker took paper documents to the worker's home in Huntsville, which is against Army regulations.
Al.com reports that officials believe the probability is low that the documents were used for illegal purposes. Authorities did not release additional details, citing the ongoing investigation.
The employees who were affected will be provided with a credit-monitoring service.
