Narrative:

While practicing maneuvers at approximately 2;000 feet while on flight following; [TRACON] advised us that an aircraft was moving at 130 knots behind us and that we should turn immediately to the south. We did so. The other aircraft then followed us in the left turn. We continued to try to evade them by turning tighter and lowering our altitude. The other aircraft continued to follow us. I was extremely concerned they were trying to hit us intentionally. I asked [TRACON] if we could be cleared into class B airspace because we could not get away from them. They denied our request. I asked the controller if they were talking to the other aircraft; he said they were not. I asked if I could get any information about the aircraft; the controller said; since the aircraft was squawking VFR; they had no information on the aircraft. I later asked the controller if there was anything we could do to report the incident and he said there was not.when we returned to [our home airport] I heard [another pilot] reporting inbound from the area we were just in. I suspected it might be him. When he landed I approached the pilot of aircraft Y. He immediately asked if we were just in [the area] doing circles. I asked if that was him following us in the turns. He said it was. I told him that it was extremely dangerous and that he scared my student and I a lot.
