Narrative:

It was VFR and we were on the valre 4 arrival between valre and bayse; descending through 8;000 ft for 6;000 ft; when ATC urgently commanded us; 'take a 30 degree left turn for traffic.' I immediately replied to the request; when ATC urgently replied; 'stop descent and hold altitude.' we had already descended below 8;000 ft; and I replied; 'holding 7;500 ft'; as I hit the altitude hold button and dialed 7;500 ft. Neither one of us recalls any TCAS indication of traffic; and as soon as ATC tried to call out traffic we got a double RA. The first command was to 'descend' followed by a reversal to 'climb; climb.' as the first officer immediately disengaged the autopilot and followed the commands; I caught a reflection off the C-172 and told the first officer; 'I have the traffic keep climbing. Keep climbing!' as it went under us; I announce to ATC; 'RA climb;' in which ATC responded; 'traffic crossing at 7;300 ft.' we cleared the C-172 by only 200 ft; which was way too close! After clearing the conflict; we were re-cleared down to 6;000 ft and back direct to bayse. A few moments later; ATC turned us over to the next controller and thanked us for the help. I replied; 'no problem; but that was too close for comfort!'

Title: A Corporate aircraft descending on the VALRE Arrival to HPN took evasive action to a TCAS RA during a near miss at about 7;500 FT.

Narrative: It was VFR and we were on the VALRE 4 arrival between VALRE and BAYSE; descending through 8;000 FT for 6;000 FT; when ATC urgently commanded us; 'Take a 30 degree left turn for traffic.' I immediately replied to the request; when ATC urgently replied; 'Stop descent and hold altitude.' We had already descended below 8;000 FT; and I replied; 'Holding 7;500 FT'; as I hit the altitude hold button and dialed 7;500 FT. Neither one of us recalls any TCAS indication of traffic; and as soon as ATC tried to call out traffic we got a double RA. The first command was to 'DESCEND' followed by a reversal to 'CLIMB; CLIMB.' As the First Officer immediately disengaged the autopilot and followed the commands; I caught a reflection off the C-172 and told the First Officer; 'I have the traffic keep climbing. Keep climbing!' As it went under us; I announce to ATC; 'RA CLIMB;' in which ATC responded; 'Traffic crossing at 7;300 FT.' We cleared the C-172 by only 200 FT; which was WAY too close! After clearing the conflict; we were re-cleared down to 6;000 FT and back direct to BAYSE. A few moments later; ATC turned us over to the next Controller and thanked us for the help.
