Austin, USA: Two people have been arrested in the death of a college student from Saudi Arabia whose remains were found alongside a motorway in a Southern California desert city, the Los Angeles Times reported on Sunday.

Abdullah Abdul Latif Al Kadi, 23, was last seen at his home in the Los Angeles suburb of Reseda on September 17. Authorities discovered his body in Palm Desert, roughly 200km to the southeast, on Thursday. His body was identified on Friday.

Police declined to release details on the arrests and were planning a news conference on Monday, the newspaper reported.

The FBI had been assisting the Los Angeles Police Department in the investigation into Al Kadi, an international student at California State University, Northridge.

Broadcaster KCBS-TV has reported that Al Kadi sold one of his cars, an Audi worth about $52,000 (Dh191,011) on Craigslist around the time of his disappearance.

The Los Angeles Times has reported that his cellphone had been traced to the city of Beaumont, some 129 km east of Los Angeles, but that it had been deactivated.
