I was training on Local Control and Aircraft X was switched to me from Approach. As soon as Aircraft X checked in; I issued traffic 11 o'clock 2 miles northwest bound 2;700 feet climbing to 3;300 feet. I then called over to Approach and informed them I was climbing the IFR Aircraft X to 3;300 feet. Aircraft X said how that's nice of them they are going underneath. The other aircraft had climbed to 3;000 feet and Aircraft X was leaving 3100 feet. I'm not too knowledgeable on getting new procedures; but something where planes don't cross [over] final Approach fix without talking to Approach or the Tower.
AFW Tower Local Control reported an unidentified VFR aircraft climbed into the final approach course of an arrival causing a NMAC.
