Neighbors in the 12700 block of Newport Avenue reported hearing a loud boom around 9 a.m., officials said.
Responding deputies interviewed and detained a homeowner at the location. They say they found debris from what looked like an explosion in the rear of a unit in the condominium complex. The bomb squad was called in and they say they found a pipe bomb and other potentially explosive materials.
Newport Avenue was closed in both directions from Wass Street to Warren Avenue as officials investigated.
Officials say it is possible the 38-year-old man may be linked to a handful of small explosions that have occurred in the Tustin area over the last few weeks. He is expected to face charges of possessing explosive materials.
