Narrative:

Flight tpa to lga, jun/sun/92, approximately PM45 local, 31 NM southwest of lga. During descent to assigned altitude, at 10000 ft MSL, ATC reported traffic at 12 O'clock and 9500 MSL. We reported negative contact. Passing 10300 in descent received TCASII TA followed almost immediately by an RA (apparently from the previously called traffic). TCASII commanded a 2000 FPM climb. We climbed back to 10500 and received 'clear of conflict' from TCASII. Advised ATC of situation and altitude deviation. We never had visual contact with traffic.
