Redding police arrested 28 people in May as a result of investigation into three storage unit burgaries in Redding and Shasta Lake, police announced Friday.
The burglaries netted a large amount of property, including 28 firearms, many of which have not been recovered.
Police arrested Edward Harsh, 37, of Redding May 2 in connection with the April 9 theft of a gun safe with 27 weapons.
Harsh was released from jail after leading officials to the missing safe, but refused to tell police what happened to the weapons.
He was later arrested on drug charges after running from a Shasta Lake house where a warrant was being served on the home's owner.
In addition to Harsh, 27 people were arrested on charges that included drug possession, possession of stolen property, burglary, parole violation, probation violation and child endangerment.
Two children were placed with child protective services.
