I was informed of a close call between parachute jumpers and a VFR aircraft. I was not aware that the VFR had come close to the jumpers until informed by the jump aircraft when it was climbing for his next pass. I noticed a VFR aircraft when the drop plane gave his one minute prior to releasing jumpers call. I gave the traffic information to the drop plane and the pilot elected to hold the jumpers and perform a 360 degree turn to allow the aircraft to pass over the aircraft. When the drop plane was turned back towards the airport; I once again updated him on the position of the VFR aircraft. The drop plane reported him in sight and released the jumpers.On the next pass; the drop plane informed me that after the jumpers were released; the VFR aircraft turned back towards the jumpers in what appeared to be a deliberate move and passed within 50 feet of the jumpers.
ZBW Controller reported a parachute jump aircraft had a near miss between their jumpers and another unidentified VFR aircraft.
