Boulder police are investigating the robbery Friday night of a Gunbarrel marijuana dispensary, allegedly by a man and a woman wielding machetes.

Boulder police Sgt. Michael Everett said police were called to a medical marijuana dispensary in the 6700 block of Lookout Road, west of the Diagonal Highway, around 7 p.m. There were customers and employees in the dispensary, which was open for business at the time of the robbery. No one was injured.

According to police radio traffic, the suspects took “all the marijuana.” Everett said the case remains under investigation, and he could not say how much of the drug was taken or whether anything else was stolen.

The suspects are described as a man with blond hair wearing a dark hoodie with a black bandanna over his face and a woman in a black and green ski mask. The suspects fled in a car heading west. Boulder police and tracking dogs searched for the suspects, but officers could not find them, Everett said.

Earlier this year, the city of Boulder had to apologize to medical marijuana businesses after it accidentally published a map showing the locations of growing operations, most of them in the Gunbarrel area. The locations of growing operations are confidential under state law because of the risk of theft.

However, dispensary locations are a matter of public record (and usually well marked) because they are retail businesses.
