The arrests are part of an ongoing investigation into illegal drug activity at Edmond apartment complexes, Chu said
Wednesday, six people were arrested at Rolling Green Apartments, 400 E Danforth Road, where marijuana, steroids and guns were found.
"This morning was the same type of raid as the sweep we did yesterday," Chu said.
"It was basically due to the same complaints we'd had at both apartments about increased gang activity. We felt like action was needed."
Chu said a helicopter from U.S. Immigration and Customs Enforcement was used to assist law officers on the ground.
She would not comment on the possibility of future raids.
"We have to keep these things quiet or they're not effective," she said.
