Singapore Armed Forces (SAF) suffered a data breach in this incident, the training centre had uploaded pictures taken at the recruits' graduation ceremony to Facebook.
However, there was a link in there that showed the troops' pictures and ID card numbers.
When the error was discovered, BMTC promptly withdrew the link to the portraits.
