A Petaluma man was held on $1 million bail Tuesday after police and FBI agents found pipe bombs at his home and materials to make additional explosive devices.
Sheriff's deputies detonated two live bombs and two partially constructed devices outside the Quarry Street home, Petaluma police Lt. Tim Lyons said.
The street through the northeast Petaluma neighborhood remained closed late Tuesday more than 24 hours after the incident began to unfold. Police and FBI officials said there was no current threat to the neighborhood but continued to search the home late Tuesday for evidence.
Ismail Moylan, 30, was arrested on suspicion of possessing a destructive device. He is scheduled to be arraigned in Sonoma County Superior Court on Wednesday morning.
Moylan, who police said also goes by the name Ismail Aljamal, initially was held in Sonoma County Jail on $250,000 bail. His bail was hiked to $1 million after police requested the increase in an attempt to keep him from being released, Lyons said.
Moylan has lived in the subdivision near Corona Road for about 15 years, said neighbors. He manages a family-run religious publishing company from his home called Sidi Muhammad Press, according to the company's website.
FBI agents joined the investigation Tuesday morning after three pipe bombs were found. Later in the day police requested additional FBI help.
"We're calling more FBI out to take a better look at the suspect's history, based upon items found inside the residence," said Lyons. "They're (FBI agents) looking at the whole incident, making sure there's nothing else to this."
FBI bomb technicians, its CSI evidence collection team, a commander and other agents were joining the effort late Tuesday afternoon, said FBI Special Agent Peter Lee, agency spokesman.
"We're sifting through the evidence," Lee said.
