(AP) BURBANK, Calif. – Los Angeles County Sheriff’s Department officials and other law enforcement personnel searched a rugged mountain area Saturday for an FBI agent who had not been seen for more than 24 hours and was said to be despondent and possibly suicidal.

Los Angeles-based Special Agent Stephen Ivens was last seen by family members Thursday evening, KABC-TV reported. He left his Burbank home the next morning on foot and hasn’t been seen since, FBI officials said at a news conference.

For computer users, a few mouse clicks could mean the difference between staying online and losing Internet connections this summer.

Unknown to most of them, their problem began when international hackers ran an online advertising scam to take control of infected computers around the world. In a highly unusual response, the FBI set up a safety net months ago using government computers to prevent Internet disruptions for those infected users. But that system is to be shut down.

The Obama administration committed more than $500 million in taxpayer money to a maker of solar power panels despite repeated red flags about the company’s viability, NBC News’ Lisa Myers reported Wednesday.

The FBI raided the Silicon Valley headquarters of the company, Solyndra, last week, investigating whether the government was misled when it loaned the company $535 million in taxpayer funds. Solyndra officials say they are cooperating with the investigation.

Solyndra received the loan guarantees in 2009 as part of President Barack Obama’s promise to create millions of so-called “green” jobs. But last month, Solyndra declared bankruptcy, laying off all 1,100 workers.

There were two separate warnings that an American businessman was plotting a terrorist attack in India with the Pakistani extremist group that carried out the Mumbai assault, NBC News confirmed Saturday.

But the second warning, given by the man’s wife to the U.S. Embassy in Islamabad just a year before the attack, was never passed to the FBI in New York, according to U.S. law enforcement officials.

The November 2008 attack in Mumbai left 166 people dead and severely frayed relations between nuclear-armed India and Pakistan.

WASHINGTON — A Justice Department investigation has found that FBI agents, including several supervisors, cheated on an important test covering the bureau’s policies for conducting surveillance on Americans.

Justice Department Inspector General Glenn Fine said Monday that his limited review of allegations that agents improperly took the open-book test together or had access to an answer sheet has turned up “significant abuses and cheating.”

Fine called on the bureau to discipline the agents, throw out the results and come up with a new test to see if FBI agents understand new rules allowing them to conduct surveillance and open files on Americans without evidence of criminal wrongdoing
