The three-alarm blaze was called in at 4:30 Wednesday morning near Market Street and 14th Street, as the VIP Pedicabs Red Barn warehouse was engulfed in flames. San Diego Deputy Fire Chief for Operations Dan Eddy was on scene that morning and said: "Initially, when our first crews got on scene, this thing was ripping stem to stern, so it was goin' pretty good!" Lithium batteries for the pedicabs were exploding, intensifying the danger. No major injuries resulted, however one person was treated for burns and a firefighter suffered a shoulder injury.
