Two men have been arrested on suspicion that they tried to kill homeless people by starting a fire in an Eagle Rock homeless camp.

The Los Angeles Police Department arrested Bryan Araujocabrera of Pacoima and Daniel Nogueira of Eagle Rock, both 25, on Saturday. They're accused of starting an Aug. 25 brush fire on the Eagle Rock and Glendale border, which mushroomed to 45 acres, shut down the 2 and 134 Freeways for hours and took more than 300 firefighters nearly 48 hours to bring under control, according to the L.A. Fire Department. One firefighter sustained a non-life threatening injury, the department said.

The LAFD said its investigators used burn patterns, witness statements and surveillance videos to determine "the fire was an intentional act related to a homeless encampment near the origin of the fire, and that those living in the encampment were specifically targeted by the suspects."

On Wednesday, the LAPD planned to present the case to the Los Angeles County District Attorney's office, said spokeswoman Det. Meghan Aguilar. The district attorney will decide whether to bring charges against the two suspects.

"Regarding Daniel Nogueira, the case is under review," district attorney spokesman Greg Risling told KPCC/LAist in an email.

With regard to Araujocabrera, "our office has asked for further investigation," he said. Risling declined to provide further details.

Noguiera posted $1 million bond and was released Sunday. Araujocabrera was being held on the same amount, but it is unclear if he has posted bail.
