Last month, the St. Johns' Smoke Buddy pot cart caught headlines with its loophole-exploiting scheme: Selling containers, then "giving away" pot to fill them.

The cops admitted at the time they had no interest in paying the cart a visit, so long as its owners weren't toting around more than an ounce of cannabis, the legal limit for public possession. But police ended up visiting the cart anyway today—after it was robbed.

Here's the Portland Police Bureau's run-down.

On Thursday September 10, 2015, at 10:20 a.m., North Precinct officers responded to North Alma Avenue and Willamette Boulevard after the report that a suspect stole marijuana from the Smoke Buddy mobile marijuana cart.

As officers were responding to the scene they learned that an African American male suspect fled the area in dark-colored SUV.

Officers arrived and learned that a second suspect was detained by the cart operator so she was taken into custody. The second suspect is a 34-year-old female.

Officers learned that the victim was opening up the trailer for the day when he saw the unidentified male suspect and the female suspect walking towards the trailer. The male suspect tried to open the trailer door with the victim inside and a struggle ensued. The male suspect displayed a knife and ran over to the trailer owner's vehicle, where the second owner was seated inside. The male suspect grabbed some items from the trunk of her vehicle while the female suspect jumped on the victim's back.

The victim was able to get her off of his back but she grabbed a stick and began swinging at him. The victim grabbed his own stick and fought her and the male suspect off and the male suspect ran to the vehicle and drove away, leaving the female suspect behind.

The victim did not receive any notable injuries during the robbery.

Robbery detectives are continuing to investigate and updates will be provided when they become available.

The robbery may give Smoke Buddy's owners second thoughts about their business model. Even if they keep on, though, the cart's probably not going to be a lengthy business venture. Smoke Buddy likely won't fly under new marijuana business licensing rules [pdf] the Portland City Council will consider next week.
