The non-injury blaze erupted shortly before 3 p.m. in the 8000 block of Peach Point Avenue, just east of Camino Ruiz and north of New Salem Street, according to the San Diego Fire-Rescue Department.
San Diego police announced on Sunday the department had arrested three teenagers in connection with the series of armed robberies that plagued at least 17.
It's unclear at this point if the robberies around the county from Tuesday night and early Wednesday morning involve the same suspects as the robberies from Wednesday night, according to police.
