SPRINGFIELD, MI -- Police raided three marijuana dispensaries near Battle Creek Wednesday, seizing 150 marijuana plants, seven handguns, ammunition and improvised explosive devices.



Investigators with the Southwest Michigan Enforcement Team (SWET) raided three businesses in the city of Springfield that are suspected of the illegal sales of marijuana under the front of a medical marijuana dispensary, according to a news release.



The raids come after several months of investigation, police say. Investigators seized 2.5 kilograms of processed marijuana and 150 plants in the dispensaries. Police also seized seven handguns, 57,000 rounds of ammunition and 21 improvised explosive devices (IEDs) at the homes of the suspects, who live in Kalamazoo and Barry Counties.



The Michigan State Police Bomb Squad removed and disposed of the IEDs.



SWET is working with Calhoun County prosecutors in filing charges against the business owners and employees.
