Yes, this is true. On Friday night (Oct 17th), a group of burglars tunneled through the wall of L & Z Jewelry located in 1000 block of S. Baldwin Avenue in Arcadia, California, and stole cash and jewelry. This happened hours before the multi-million dollar heist at the Louvre Museum in Paris. Officers didn't hear about this incident until about 10:45 am on Saturday morning when the owner Feihong Zhoa called in a report for commercial burglary. The officers then determined that the burglary happened between 7pm Friday and 10 am on Saturday. The police statement include that the unknown subjects had disabled the cameras and alarm system before they accessed the roof of an adjacent vacant business and forced their way in, once they were in they then made a tunnel into the jewelry store's safe room, which is where they stole jewelry and cash. Zhao said that an estimation of half a million dollars ($500.000) worth of diamonds, gold, and money was stolen. This case is still under investigate so these are all the details that have been released to the public.

This is where it gives a brief overview of what occurred, it also gave dialogue of what the owner Feihong Zhao thought of the incident. it was written by Missael Soto and Alex Zapata. Missael Soto is a producer with the NBCLA ? Telemundo 52 digital team. Alex Zapata doesn't have that much information written on his profile but he was also co-publisher. I saw no bias in this article,

This article is very similar to the one I posted above this one. It gives very similar information but this one includes video footage of the damage the was caused and what the scene actually looked like. It was written by Owen Scott who is a US News Reporter, specialized in politics, crime, and culture. I will say this articled did use the idea that this robbery was out of inspiration of the Louvre heist but that is a theory that has been floating around and has not been debunked or proven true.

This is another article that has very similar information, the information is more simplified but gives the overview of what happened. It was written by Dean Fioresi who is a Web Producer at CBS Los Angelas. He covers breaking news throughout Southern California. like the last two articles, I saw no bias.
