Narrative:

A helicopter was climbing eastbound. I was issuing traffic ahead when I noticed the data block of an A320 rapidly descending through the class echo in close proximity to the helicopter. I had almost no time to issue traffic before the A320 passed 200 ft over the top of the helicopter. I gave a wake turbulence warning and asked if he saw the A320. I called the radar controller and asked if the A320 saw the helicopter. All he/she said was that the A320 was past him; which was non-responsive. I don't know who caused this near midair collision; but it developed so fast there was barely any time to react and issue a warning. I advised our supervisor of the situation. Earlier today; another airliner flew through the class D without coordination. I don't know if it was the pilot or the controller. There seems to be no way that the A320 could not have received a RA. Someone screwed up. There needs to be more coordination from sct.

Title: MYF Controller described a NMAC involving a helicopter climbing eastbound and an air carrier arrival into SAN. The reporter listed coordination failures with SCT as contributing to the event.
