Narrative:

I was transitioned to cdw for clearance through delta enroute to ZZZ. Cdw acknowledged and approved descending transition. Target for ZZZ inbound was bingg at 2000. Aircraft Y departing N07 announces inbound. Tower advises aircraft X traffic at 2 o'clock and 3 miles and 12 o'clock 1 mile at which point aircraft X sights aircraft Y crossing approximately 200 feet below. Aircraft Y misstated position several times and then passed aircraft X at close range twice when he should have been clear of aircraft X path after initial crossing if he were on track.tower did not clear aircraft X from aircraft Y's path nor inform aircraft X that aircraft Y was misreporting location. Tower conversations did suggest the aircraft Y pilot was not following directions however aircraft X was not able to determine aircraft Y's position until near misses occurred. Near misses were not fully realized until noise abatement tapes were reviewed along with archived ATC recordings. Aircraft Y did not appear on aircraft X adsb traffic nor on traffic display.
