A nonprofit think tank has removed a study from its website that said crime increased near medical marijuana dispensaries in Los Angeles after they were closed.

Warren Robak, a spokesman for Santa Monica-based Rand Corp., says the organization is reviewing the study released last month and has removed it from circulation.

The Los Angeles city attorney's office had said the report's findings were deeply flawed and demanded a retraction.

The study, first reported by the Los Angeles Times, looked at crime reports in the 10 days before and after Los Angeles officials shuttered the pot clinics last summer after a new ordinance went into effect. The analysis showed crime increased about 60 percent within three blocks of a closed dispensary compared with those that remained open.
