An employee at Facebook's Silicon Valley headquarters has died by jumping from the fourth floor in what local police called "apparent suicide".
The city of Menlo Park, California, which is home to the social media giant's expansive campus, said that police officers, firefighters and paramedics were called at 11:30am but were unable to revive the employee.
The man, whom Bloomberg described as a software engineer, was pronounced dead at the scene. The city said that there was no evidence of foul play.
A spokesman for Facebook said: "We were saddened to learn that one of our employees passed away at our Menlo Park headquarters earlier today. We're cooperating with police in their investigation and providing support to employees.
"While the family is being notified, we have no information to share. We hope to provide an update when we learn additional information from law enforcement.
There is no indication that the incident has anything to do with the employee's role at Facebook.
