Khan Academy employees arrived to work in Mountain View on Monday morning to find that the free online academy was the victim of a major burglary.

Sometime over Sunday night thieves took 33 Apple computers from the Khan Academy office worth $40,000, police reported.

Police said the thieves "defeated the front door lock" of the popular nonprofit's offices on the 1900 block of Landings Drive, near Google headquarters, to make the theft.

Police say there are no suspects or witnesses at this point.
