Three asset forfeiture lawsuits were filed by federal prosecutors against properties housing marijuana operations in Santa Barbara County, the U.S. Attorney General's Office in Los Angeles announced today.

Federal authorities also executed search warrants at four locations and have sent letters warning people associated with 10 other illegal marijuana stores in the county, according to federal officials.

The three properties are located Santa Barbara and Summerland were marijuana is grown or the stores are currently operating, say officials.

The buildings named in the forfeiture lawsuits are Miramar Collective on Ortega Hill Road in Summerland, which officials say was generated $840,000 in profits in 2009, and whose owner is currently being prosecuted by the Santa Barbara District Attorney's Office.

Also Pacific Coast Collective on North Milpas in Santa Barbara, which its operators say is a non-profit business. But authorities allege that the business doesn't have a non-profit status for taxes, federal official stated. The operator is being prosecuted by the Santa Barbara District Attorney's Office.

A search warrant was executed today at an indoor marijuana farm on East Haley in Santa Barbara.   Federal authorities claim that substandard and unpermitted equipment was used in that operation.
