The group entered by the main (south) entrance. They first took control of the radio room. In the process, they disarmed 5 guards & handcuffed their hands & feet (one news source said it was 2 police & 3 security guards).
The commando then entered the arsenal after breaking 2 locks to get through the steel doors. They took 43 H&K G36 assault rifles (.223 caliber), 26 9mm pistols, bulletproof vests & grenades.
They left the way they came with no resistance. Official reports admitted there was insufficient security for the complex.
It was also apparent from how the commando conducted their operation that they knew how to enter the complex, how to access the radio room & where the arsenal was located.
Authorities are reviewing security cam videos to learn more about the perpetrators.
