Two boys were arrested Tuesday morning in connection with two house fires in the 1300 and 1400 block of North Olney Street on the city’s northeast side. The first fire broke out at about 1:30 a.m. and caused an estimated $25,000 in damage. The second occurred at about 6 a.m. and created $35,000 in damage. Both homes were vacant and the fires appeared to be intentionally set. The boys also are suspected of causing a dumpster fire.
