Narrative:

I was flying approaching the la coliseum; east to west. I had a tcad alert that an aircraft was approaching me from the north and behind my position (from inside the dodger stadium tfr). I gave a position report and did not hear a reply on the common la basin frequency of 123.02. I checked in with lax helicopters and asked if the helicopter had checked in with them. I was told no. I was at an altitude of 700 to 800 feet MSL. I continued west bound and observed the other traffic fly directly underneath me; approximately 100 to 200 feet below me; putting the other aircraft; [aircraft Y;] at about 300 to 400 feet AGL.the other aircraft continued to increase speed and went westbound along the 10 freeway. I contacted another helicopter [aircraft Z] to intercept in order to get a tail number. That helicopter followed the aircraft to a nearby airport where it landed. That tower provided the aircraft tail number and advised about its origin airport.
