Narrative:

I was the pilot in command of a cessna 172s; after a training flight with a student pilot working towards his private pilot's license. I was returning from the north east of the grand forks airport; approach had me enter through east ponds and handed me off to grand forks tower. Between east ponds and lagoon we descended from 2;200 to 1;500. Prior to reaching lagoon a light twin reported a near miss with a 172; stating the 172 passed 200 ft below the light twin. The light twin was inbound to the airport from the north west; flying east at the time of the near miss. The light twin was given an altitude restriction of 2;100 ft before entering the traffic pattern; and was at 2;100 at the time of the near miss.as we were descending towards lagoon; I was scanning out side; with the occasional glance inside at the ads-B. The only traffic I ever saw was in the traffic pattern several miles from my location as we descended towards lagoon. Upon reaching lagoon tower instructed me to fly west out side of the traffic pattern; along the north edge of lagoon. Once we were abeam the grand forks passenger terminal tower instructed me to make a 180 degree turn and enter into the traffic pattern following a light twin over the domes. Once we made the turn I looked for the traffic and saw the light twin on short final. Upon landing and taxiing off the runway tower asked me to call the phone number to the tower once parked. Once I was out of the plane I called tower [who stated he] felt that my aircraft could have possibly been close enough to the area to have caused the near miss. The sky was clear the visibility was unrestricted.
