Building collapse lawsuits seek to get answers, assign blame.

Bond was granted Tuesday for a South Los Angeles man charged with illegally transporting tons of explosives, including dangerous homemade devices that were detonated by police, leading to a massive explosion that destroyed a specially designed containment vehicle and injured 17 people.

Arturo Ceja III was expected to be released from federal custody at the end of the day on an unsecured $25,000 bond signed by his parents, according to the U.S. attorney’s office. He is expected to be arraigned on Aug. 2.

Ceja, 26, was arrested Saturday by special agents with the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives on a criminal complaint charging him with transporting explosives without a license. The charge carries a sentence of up to 10 years in federal prison, prosecutors said.

Ceja was initially arrested and booked after the Wednesday evening explosion on suspicion of possession of a destructive device and child endangerment, and was released after posting $500,000 bond Thursday.

State charges have not been filed against Ceja, according to the Los Angeles County District Attorney’s Office.

Ceja was taken into federal custody Saturday pending Tuesday’s initial appearance before a magistrate judge in downtown Los Angeles.

Ceja’s attorney did not immediately return a call seeking comment.

Ceja apparently planned to sell the fireworks throughout the neighborhood in celebration of the Fourth of July holiday.

The federal complaint alleges that Ceja made several trips to Nevada in late June to purchase various types of explosives that he transported to his home in rental vans.

Most of the explosives were purchased at Area 51, a fireworks dealer in Pahrump, Nevada. The complaint notes that fireworks in California can be sold for as much as four times what purchasers pay for them in Nevada.

Ceja told investigators that he purchased the homemade explosives — constructed of cardboard paper, hobby fuse and packed with explosive flash powder — from an individual selling the devices out of the trunk of a Honda in the Area 51 parking lot, according to the complaint.
