Narrative:
While working vikky radar I took a handoff from 490 on atx X at 60 on V1 northeast of mad. Shortly after the pilot checked in, I saw atx Y also at 60, northeast of atx X heading on a track that would merge with atx X , and slightly faster. I issued the traffic to atx X who advised he was IMC. I checked to see if the loves controller was working atx Y (he had taken the handoff), but was told he was not. I then called Y90 to see if they were still working atx Y and to determine if they were turning him wbound (away from atx X.) Y90 advised atx Y was turning wbound and I in turn advised them I was turning atx X sbound - which they approved. I then turned atx X on a heading of 180, away from the traffic.

Title: APCH CTLR UNAUTHORIZED UNCOORD PENETRATION OF AIRSPACE WITH ATX Y HAD LTSS WITH ATX X. SYS ERROR.
Narrative: WHILE WORKING VIKKY RADAR I TOOK A HDOF FROM 490 ON ATX X AT 60 ON V1 NE OF MAD. SHORTLY AFTER THE PLT CHKED IN, I SAW ATX Y ALSO AT 60, NE OF ATX X HDG ON A TRACK THAT WOULD MERGE WITH ATX X , AND SLIGHTLY FASTER. I ISSUED THE TFC TO ATX X WHO ADVISED HE WAS IMC. I CHKED TO SEE IF THE LOVES CTLR WAS WORKING ATX Y (HE HAD TAKEN THE HDOF), BUT WAS TOLD HE WAS NOT. I THEN CALLED Y90 TO SEE IF THEY WERE STILL WORKING ATX Y AND TO DETERMINE IF THEY WERE TURNING HIM WBOUND (AWAY FROM ATX X.) Y90 ADVISED ATX Y WAS TURNING WBOUND AND I IN TURN ADVISED THEM I WAS TURNING ATX X SBOUND - WHICH THEY APPROVED. I THEN TURNED ATX X ON A HDG OF 180, AWAY FROM THE TFC.
