Surveying the damage, Pizza Corner manager Saowanee Srichokchai said damage likely would cost more than 500,000 to repair. Flames destroyed the stores’ computer systems, an ice cream freezer and interior decorations.
Pizza Corner, Cream & Fudge and Coffee World were gutted by fire Dec. 12.
A security guard said he called authorities after seeing large amounts of smoke pouring out of one of the shops and then heard two explosions that caused flames to spread quickly.
Fire investigators are working on the assumption faulty wiring was at fault for the blaze, but are still investigating.
