Victorville, California police determined local resident Mohamed Elrawi is a radicalized Muslim and arrested him for attempted murder after he allegedly chased a neighbor with a sword and yelled “I would die and kill for Allah.”

Victorville police responded to an apartment complex shortly after 5 p.m. Monday after someone called about a person with a weapon. Police believe Mohamed Ahmed Elrawi, 57, was in a dispute with his neighbor when he threatened to kill him before fleeing the scene, the Victorville Daily Press reports.

Sheriff Sgt. Dave Burgess told the news site the neighbor escaped unharmed, and police obtained a search warrant for Elrawi’s apartment, where “a Quran and other items were located …, leading investigators to believe Elrawi may have been a radicalized Muslim.”

Burgess said authorities also staked out Elrawi’s home and waited for him to return.

“Sheriff’s Intelligence Division was notified of the investigation,” Burgess told VVNG. “Deputies began surveillance and at a little after midnight, Elrawi returned to his apartment and was quickly taken into custody without incident.”

Apartment complex resident Yolanda Goring, 25, said she heard the commotion Monday night and went outside to find Elrawi with a sword, threatening other residents.

“My kids were sleeping when I heard a lot of noise,” Gorning said, adding that Elrawi alleged one of the neighbors had stolen something from him. “I went outside and saw that (Elrawi) had a big sword that he was swinging back and forth. I went back inside but I could still hear yelling and arguing and I heard (Elrawi) telling someone that he was going to kill him.”

Elrawi’s recent run-in with law enforcement isn’t his first.

According to the Daily Press:

The director of the High Desert Islamic Society in Victorville, Yousef Farha, told the Daily Press on Tuesday that Elrawi is a former member of that mosque. Elrawi was banned from the mosque in January after a small group — Elrawi included — attempted to “hijack” the mosque, according to Farha.

Farha said Elrawi also threatened his life and police informed Farha to “watch out.”

“Mentally he is not stable,” Farha said. “(Elrawi) — just about two or three years ago — his son committed suicide and that contributed to his situation. He doesn’t care about religion. He just goes to mosque for the heck of it.”

A “Mohamed Ahmed Elrawi” was previously charged with attempted murder in this county and later convicted Feb. 10, 1999 for felony spousal abuse in a plea bargain, court records show. It wasn’t clear Tuesday afternoon whether Elrawi was the same person. In that case, the man was sentenced to six years in prison and credited with 605 days for time served and good behavior — 89 of which were spent at Patton State Hospital, a forensics psychiatric facility, in San Bernardino, court records show.

Elrawi is in the High Desert Detention Center on a $500,000 bail.

Police in Melbourne, Florida were also busy this week vetting potential terrorists when they arrested United Arab Emirates citizen Hamid Mohamed Ahmed Ali Rehaif, who was kicked out of the Florida Institute of Technology in the fall of 2014, News 6 reports.

Rehaif was supposed to leave the country within 30 days, and became an illegal alien when his student visa expired.

Agents with the U.S. Immigration and Custom Enforcement’s Homeland Security Investigations and the FBI learned Rehaif had been living out of a Melbourne hotel for the last two months – paying more than $11,000 in cash for room fees – and that he had been firing weapons at local gun ranges, according to the site.

Agents located handgun and rifle ammunition in Rehaif’s hotel room and a storage unit, police records show, but no weapons. Rehaif allegedly admitted to owning several weapons he fired at two gun ranges, but said he recently sold them.

He was arrested for possession of ammunition by an unlawful or illegal alien, a 10 year felony, and waived his detention hearing. He’s scheduled for a preliminary hearing in U.S. District court Monday, News 6 reports.
