Narrative:

Approximately 25 mi northeast of ind at FL230; crj-200 was given a left turn direct iiu then as filed. A short time later; we were issued a clearance to climb and maintain FL250. Climbing out of approximately FL240; center controller urgently requested an immediate increase in our climb and a l-hand turn to a heading of 090 degrees. He then issued a traffic alert. Around FL242; we received a TCAS alert to descend then increase descent. As the PF; first officer appropriately initiated a descending l-hand turn away from the target per the aural and visual guidance from the TCAS. The other aircraft was noted to be approximately 2 1/2 mi to our 3-4 O'clock position and 100 ft above our flight path. Once we were clear of the other aircraft; we received ATC clearance to return to our original heading and altitude. Center controller made a statement something like; 'sorry; that wasn't supposed to turn out like that' and then asked if everything was ok. We informed the controller that everything was back to normal onboard and continued on. The flight attendant and I communicated via the intercom about the incident. I explained to her what had taken place and she stated that the passenger never indicated that they were aware of anything abnormal during our avoidance maneuver.
