Wall Tiles Are Coming Loose

[Unregistered]

I've recently drilled a couple of holes in my Mother's bathroom wall tiles to enable me to install a new striplight. Within a couple of days numerous tiles have become loose and a few have even cracked. Would my drilling have caused this? I presume it must have done as it seems too much of a coincidence. After drilling and putting up the new light the wall looked fine and the problem arose after a day or two.
Any help would be greatly appreciated.

Tiles have been up since the property was built approx 15 - 20 years ago.

Studwall, dot and dabbed, or render and skim do you know?
