According to the police log, the LAPD responded to 13 alarm calls at the building in the year prior to the heist, and all of them were determined to be false alarms. Notably, one occurred just before 11:30 p.m. on March 30, the night before the heist. A patrol car arrived at the warehouse minutes later and deemed it a false alarm.
Another alarm rang at the building on at 4:36 a.m. on Easter, according to the log. Hours later, the log shows, a police car was dispatched to the property, a supervisor was notified and a report was written. The log does not indicate what the police found. However, a resident at the neighboring Tahitian Mobile Home Park
previously told The Times that FBI agents visited her the day after the burglary and asked if she “saw or heard anything suspicious around 4 a.m.” on Easter. (The woman said she was asleep at the time and did not.)
At 7.22 a.m., another alarm rang at GardaWorld’s warehouse and a police car responded about 45 minutes later; the LAPD log shows it was considered a “valid alarm.” Finally, an alarm rang at 3:51 p.m. and a police car arrived around 4 p.m. in response. This was deemed a false alarm, according to the log, the details of which were first reported by TMZ.
According to Aria Kozak, chief executive of L.A.-based security services company Elite Interactive Solutions, the false alarms triggered before the heist could have been the result of criminals testing the security apparatus at the building.
“In that particular case, the false alarms could just be a little window into the criminal activity,” he said. “They are very capable and smart and they will look for the soft or weak spot.”...snip
