TRACON final controller took a point-out on and approved an aircraft to traverse his airspace. The north radar controller turned the aircraft without coordination and created an less than standard separation incident. The DH8 that was on final got a TCASII RA and followed it in a climb even though the final controller was turning him for separation.

Narrative:
Working final radar control position. Aircraft approved to enter final radar airspace on point-out, being controled by north radar controller. Without coordination, north radar controller turned aircraft in final radar airspace while final radar controller turned aircraft #1. This created conflict. Controller attempted to turn aircraft away from each other and crew of aircraft #1 followed TCASII RA and climbed. To prevent future similar sits we should 'work' airplanes in our own airspace and not accept point-outs on aircraft that will be operating in close proximity to other aircraft.

Title: TRACON FINAL CTLR TOOK A POINT-OUT ON AND APPROVED AN ACFT TO TRAVERSE HIS AIRSPACE. THE N RADAR CTLR TURNED THE ACFT WITHOUT COORD AND CREATED AN LTSS INCIDENT. THE DH8 THAT WAS ON FINAL GOT A TCASII RA AND FOLLOWED IT IN A CLB EVEN THOUGH THE FINAL CTLR WAS TURNING HIM FOR SEPARATION.
Narrative: WORKING FINAL RADAR CTL POS. ACFT APPROVED TO ENTER FINAL RADAR AIRSPACE ON POINT-OUT, BEING CTLED BY N RADAR CTLR. WITHOUT COORD, N RADAR CTLR TURNED ACFT IN FINAL RADAR AIRSPACE WHILE FINAL RADAR CTLR TURNED ACFT #1. THIS CREATED CONFLICT. CTLR ATTEMPTED TO TURN ACFT AWAY FROM EACH OTHER AND CREW OF ACFT #1 FOLLOWED TCASII RA AND CLBED. TO PREVENT FUTURE SIMILAR SITS WE SHOULD 'WORK' AIRPLANES IN OUR OWN AIRSPACE AND NOT ACCEPT POINT-OUTS ON ACFT THAT WILL BE OPERATING IN CLOSE PROX TO OTHER ACFT.
