Narrative:

I was working east radar and took a handoff on aircraft X. This was immediately followed up by a call from the sector advising me of traffic 20 miles ahead at 10300 ft. About 3 miles east of lbv. This traffic was northwest-bound and would not be a factor. The sector advised me that aircraft X was released for lower. After I got off the line; lbv sector called me to coordinate with an arrival that was going south of a prohibited area and coming towards my airspace. We had a back and forth on the line when I suddenly realized that aircraft X and the VFR traffic were a factor. I immediately hung up and issued a traffic alert with a left turn. Aircraft X advised that they responded with a turn and descent. I was able to review the tapes and the VFR aircraft flew passed lbv at 10300 ft. Made a left 360 degree turn back into aircraft X; causing a near midair collision.1) I should have told the center to descend aircraft X to 8000 instead of taking the information that he was my control. I also; should not have gotten distracted with a pointless coordination of an aircraft that never got in my airspace.
