CONDO RESIDENT THREW DOWN KILLER BATTERY FROM HIGH FLOOR, SHATTERS GLASS SHELTER

I live in this rented unit and I have informed the condo management roughly 1 hour after it happened (it happened around 1120 am today) , but we couldn’t find out who did this. We found a Li-on battery on top of the panel, which we suspect has shattered the glass.

I guess my ass is covered by the clause in tenancy agreement where it states i only pay up to 100 dollars for major repairs. But i am really pissed by whoever did this and i suspect it is the same dude who has been throwing cigarette butts to the very same glass panel non-stop since i moved in. So i really want to see him dealt with.

Anyone knows what i should do to help identify the offender or prevent it from happening again. NEA? Police? I felt the condo managment hasn’t been very helpful coz they are just like “ok, i’ll let my boss know and tell the residents not to throw”. Thanks
