 Not a very nice thing to happen to anyone.

 Theres a nose-wheel-strut locking pin that SHOULD be in place
 when the aircraft is not being used.
 Its usually on a bar about 5 foot long ( for easy removal from ground level)

 However to purposely cause the landing gear to go "up" is very hard
to do for someone in the cockpit during push-out of a hangar.
The person 'on the brakes' in the cockpit would be a 'responsible' person
and so it must have been 100% accident. You just dont go over to
the gear lever and pull it out and up !!  which leads to suggest
either major failure in nose wheel support or "where was the pin?"
