Narrative:
At XX02Z, I took the south arrival position combined with west and 1/2 of fv position. The previous controller briefed me that an aircraft over runway 17N was climbing to 13500 ft with jumpers and needed to be pointed out to ZDC and ZNY. I made the point out to ZDC but ZNY didn't answer. Then air carrier X, who was on vectors for a visual, asked to be vectored out for the ILS to get time for them to finish in the back. I said no problem and tried the point out again. No answer again. The south departure position 'approval requested' a slow climb to ditch, which I approved and had to watch traffic for it, a VFR overflt which was passing over runway 17N as the jump aircraft climbed into ZNY space. I tried the point out again and as I did, I saw unknown traffic, unknown Y at 2600 ft in front of air carrier X. I transmitted 'air carrier X heavy, traffic alert, 12 O'clock, 1 mi, sbound, 2600 ft unverified.' he said 'we don't see him, but we have a resolution and we're following it.' I said 'roger.' as he passed over the target air carrier X reported the aircraft in sight. I said roger and turned him onto final. He reported the airport in sight and I cleared him for a visual approach. He then said 'that was a near miss and I'll have to file a report.' I said roger and advised the supervisor. Callback conversation with reporter revealed the following information: asked reporter if the unknown aircraft had been observed in the class 'B', and was told that he was unsure but that the aircraft appeared to be on the edge of it. When asked if the B767 had taken evasive action, the reporter indicated that they had the traffic in sight and leveled off until clear of the traffic.

Title: NMAC BTWN ACR X AND UNKNOWN Y.
Narrative: AT XX02Z, I TOOK THE S ARR POS COMBINED WITH W AND 1/2 OF FV POS. THE PREVIOUS CTLR BRIEFED ME THAT AN ACFT OVER RWY 17N WAS CLBING TO 13500 FT WITH JUMPERS AND NEEDED TO BE POINTED OUT TO ZDC AND ZNY. I MADE THE POINT OUT TO ZDC BUT ZNY DIDN'T ANSWER. THEN ACR X, WHO WAS ON VECTORS FOR A VISUAL, ASKED TO BE VECTORED OUT FOR THE ILS TO GET TIME FOR THEM TO FINISH IN THE BACK. I SAID NO PROB AND TRIED THE POINT OUT AGAIN. NO ANSWER AGAIN. THE S DEP POS 'APPROVAL REQUESTED' A SLOW CLB TO DITCH, WHICH I APPROVED AND HAD TO WATCH TFC FOR IT, A VFR OVERFLT WHICH WAS PASSING OVER RWY 17N AS THE JUMP ACFT CLBED INTO ZNY SPACE. I TRIED THE POINT OUT AGAIN AND AS I DID, I SAW UNKNOWN TFC, UNKNOWN Y AT 2600 FT IN FRONT OF ACR X. I XMITTED 'ACR X HVY, TFC ALERT, 12 O'CLOCK, 1 MI, SBOUND, 2600 FT UNVERIFIED.' HE SAID 'WE DON'T SEE HIM, BUT WE HAVE A RESOLUTION AND WE'RE FOLLOWING IT.' I SAID 'ROGER.' AS HE PASSED OVER THE TARGET ACR X RPTED THE ACFT IN SIGHT. I SAID ROGER AND TURNED HIM ONTO FINAL. HE RPTED THE ARPT IN SIGHT AND I CLRED HIM FOR A VISUAL APCH. HE THEN SAID 'THAT WAS A NEAR MISS AND I'LL HAVE TO FILE A RPT.' I SAID ROGER AND ADVISED THE SUPVR. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: ASKED RPTR IF THE UNKNOWN ACFT HAD BEEN OBSERVED IN THE CLASS 'B', AND WAS TOLD THAT HE WAS UNSURE BUT THAT THE ACFT APPEARED TO BE ON THE EDGE OF IT. WHEN ASKED IF THE B767 HAD TAKEN EVASIVE ACTION, THE RPTR INDICATED THAT THEY HAD THE TFC IN SIGHT AND LEVELED OFF UNTIL CLR OF THE TFC.
