A group of burglars drilled through two safes at a Glendora jewelry store, stealing over $800,000 worth of diamonds, gold, and cash. The thieves, allegedly part of an international 'burglary tourism' ring, were caught on video. Four Colombian nationals were arrested for surveilling and burglarizing homes in Glendale. In a separate incident, robbery suspects stole $8,000 worth of items in 30 seconds at King of Prussia Mall. The burglars were able to bring heavy equipment into the shop and spent six hours cutting through steel safes.
