Bellevue Police are working with The Shops at the Bravern security to improve its ability to curb thefts following four at the high-end shopping center over the past month.

Bellevue Police Ofc. Seth Tyler said a detective has been assigned to those four shoplifting cases due to the high cost of the items stolen, including $8,000 in merchandise taken from Gucci during two grab-and-runs there on July 19 and Aug. 3. Two other thefts were reported at Salvatore Ferragamo and Tory Burch.

“We believe those suspects are the same in those cases, and we also believe they’re related to some strong-arm robberies in the Des Moines area,” Tyler said.

Police contacted Bravern security on Aug. 12, and will be working to improve their abilities, Tyler said.

“Up to this point they haven’t really had any major theft issues,” Tyler said, adding these incidents were done by organized retail thieves. “They know what they’re doing. It’s not their first time doing this.”
