Someone is making a fool of himself.
There are some problems with the concept:
1. Once you know the laser it is fairly easy to make an optical filter
to remove the laser light but not much else.
2. How do they detect and find the CCD (or CMOS). No answer is given,
and there is nor easy way, at least if you do not measure the
absorption spectrum of Si, but you would have a hard time
distinguishing this from other elements and you would need a light
source that could warn the photographers.
3. What they could do was to use a laser aimed at the photographers
camera as a slave flash, emitting a beam once the photographer used a
flash, but who would use a flash at that distance?
I think that either a billioner has been fooled, or he is trying to
fool the paparazzi. If some celebrity really didn´t want the paparazzi
to take pictures they would use reflective materials in their collars
and slave flashes in their hats being aimed at the photographers. It
would ruin most of the pictures.

...Ambramovich has installed an anti-paparazzi “shield”. Lasers
sweep the surroundings and when they detect a CCD, they fire a bolt
of light right at the camera to obliterate any photograph....
Wouldn't the mirror bounce the laser back???
