I really don't appreciate your sexist comment. It's one/two guys acting like jacktards. Not the woman! So behind this problem is one or two guy(s)! Now keep your misogynistic comments off the forums. Thank you.

That aside, I would definitely tell security. If you can, get a written report (for your records) because if something worse happens, like your brakes get cut and you land in the hospital or worse, they'll know it was tampering and can start investigating.

BTW, you should definitely park your bike where security can keep an eye on it and do a thorough safety check of your whole entire bike (wheels, breaks, cables, etc.) before riding your bike home.

Someone in your office dislikes you enough to go out of their way to screw with your vehicle. Can you say "hostile frenemy"? Might want to look into that.
