Denver marijuana businesses have seen an increase in burglaries during the coronavirus pandemic as the cannabis industry continues to see an uptick in crime in the city, according to police.

Allowed to continue operations as essential businesses, dispensaries and cultivations reported 10 burglaries in the first two weeks of April, Denver police said. That’s up from eight burglaries reported during the whole month of April 2019.

Burglaries of Denver marijuana businesses hit a three-year high in 2019, with 122 reported within city limits. However, statistics are up every month of 2020 from the year prior, totaling 31 reported burglaries so far.

Denver police received seven burglary reports in January (up from two the same month in 2019), six in February (up from two a year ago), and eight in March (up from four a year ago).

“We know that all of you have established new policies during this pandemic to limit the number of customers in your stores while practicing good social distancing recommendations,” Denver police said in an industry-wide bulletin Tuesday. “If you have not done so already, please take this time to incorporate additional measures to prevent a crime from occurring at your business.”
