The raid was not found until the vault was opened again the following day, according to individuals who spoke with the LA Times. The perpetrators broke in via the roof on Easter Sunday night.
How they managed to avoid setting off the alarm is unknown.
According to police commander Elaine Morales, the facility, which is located in the Sylmar neighborhood of the San Fernando Valley, is used to handle and hold cash from nearby businesses.
According to the news, very few people would have known about the substantial sums of cash kept there.
Police and the FBI are reportedly conducting joint investigations.
The burglary’s timing is similar to that of the famed Hatton Garden heist in London in 2015, which also occurred during Easter weekend. It appears that the perpetrators chose this time to escape detection because surrounding businesses were closed.
