The Cumberland County Sheriff’s office says it inadvertently posted on its Facebook page and in a message to media outlets the social security numbers of about 180 people who were arrested last week. Authorities say it’s believed that about 70 people had access to the information. The sheriff’s office said Thursday that the error was discovered within 45 minutes of the posting and the information was removed immediately. The office says the glitch was caused by a software update that automatically sends a weekly arrest report to various media outlets and posts the arrests on the office’s Facebook page. The office says the software update has been changed and will not include social security numbers in the future.
