Narrative:

While on final approach to runway 24L at lax, approach control advised aircraft at 1 O'clock would be turning behind and above us to runways 25 (there were many aircraft at 1-2 O'clock). Approximately at romen outer marker an aircraft, belly up to us in a turn southbound, crossed directly in front of us at our altitude +/-100' and 1000'-1500' in front of us. ATC said their radar showed the other aircraft did pass above and behind us. I believe both ATC and the other aircraft were looking at a widebody transport approximately 3 mi in front of us on approach to runway 24R.

Title: ACFT CROSSED IN FRONT OF ACR ON FINAL APCH.

Narrative: WHILE ON FINAL APCH TO RWY 24L AT LAX, APCH CTL ADVISED ACFT AT 1 O'CLOCK WOULD BE TURNING BEHIND AND ABOVE US TO RWYS 25 (THERE WERE MANY ACFT AT 1-2 O'CLOCK). APPROX AT ROMEN OUTER MARKER AN ACFT, BELLY UP TO US IN A TURN SBND, CROSSED DIRECTLY IN FRONT OF US AT OUR ALT +/-100' AND 1000'-1500' IN FRONT OF US. ATC SAID THEIR RADAR SHOWED THE OTHER ACFT DID PASS ABOVE AND BEHIND US. I BELIEVE BOTH ATC AND THE OTHER ACFT WERE LOOKING AT A WDB APPROX 3 MI IN FRONT OF US ON APCH TO RWY 24R.
