The explosion was reported at about 7:45 a.m. in the 6500 block of North Farmdale, right in front a 37-unit apartment complex.

LAFD spokesman Brian Humphrye says forceful blast was heard over a wide area and sent concrete debris and the electrical vault’s lid flying into the front of the complex. Multiple windows were broken, but there were no reports of fire or injuries.
