Narrative:

I was working local 1 and aircraft X checked onto my frequency; I noticed that aircraft Y was 2-3 miles south west at 1;000 feet heading towards the final northeast bound. My assist had just accepted an automated point out less than a minute before aircraft X checked on my frequency. I then issued traffic to aircraft X and at the same time my assist was asking the sct sector controlling aircraft Y what he was doing. I then noticed that aircraft Y was still on course to cross the final at about 4 to 5 miles from the airport at 1;000 feet. Aircraft X was at 2;200 feet when I gave a traffic alert traffic call that I will admit I messed up a bit; however; I tried to correct my mistake as best as I could while keyed up. Aircraft X crossed over aircraft Y at 1;700 feet; while aircraft Y was at 1;000 feet.anytime an aircraft will be operating on a final at an altitude that may affect arriving aircraft; it should be verbally coordinated between controllers along with the positive control of the point out aircraft; ensuring that it does not affect any aircraft on the final.
