Officers responded to the scene, in the 3200 block of Rainier Avenue South, at about 10:45 a.m. after receiving a 911 call about a possible robbery at the dispensary. The caller said that several armed suspects entered the business.
Additional 911 calls from inside the dispensary said that three armed suspects had robbed the business and then fled south down an alley, said Seattle police spokesman Detective Mark Jamieson.
Officers responded to the location and began searching for the suspects. All three were armed with handguns.
Jamieson said the investigation remains open and active. Anyone with information on this case is asked to call 911.
