According to SFist reader Salty, as of 8:30 p.m. the SFPD bomb squad has been stationed "[m]idway down the 1600 block, on the west side" of 39th Avenue (i.e., between Lawton and Moraga.) "Fire Chief on the scene. Ambulance still on scene. SFPD still on the scene. Bomb Squad Truck still on the scene." No word yet on any evacuations. Probably another stupid mortar from the war between the states, or whatever. Anyway, anyone in the area know what's up? Let us know in the comments. And be careful not to blow up. UPDATE: No ka-boom. Squad and sirens left a little before 9:40 p.m.
