Narrative:

Aircraft X was instructed by local control to fly over the numbers of runway xx for a left downwind to runway yy. Aircraft X turned for the numbers of runway xx as advised and flew in front of aircraft Y on an IFR approach to runway xx. Aircraft Y was at 1;400 ft and less than a mile from aircraft X. The next incident was when aircraft X was on short final to runway yy and air carrier Z; lear jet; was on final to runway xx and aircraft X was told to make a left 360. I was the controller in charge and told local control three times that his trainee had turned aircraft X head on into air carrier Z. I told him three times to instruct aircraft X to fly runway heading and go around. Local control did not respond. Aircraft X flew over the top of air carrier Z with no distance separation and 300 ft of vertical separation.ground control played a contributing factor in this event by ridiculing the local controller; laughing and telling the tower staff that the local controller had lost the picture. Ground controller's actions added to the confusion the local controller was already experiencing.
