That is ####ty. Sorry to hear man, will definitely keep an eye out for it.
How was your bike locked up? I see so many people locking bikes incorrectly that leads to stolen bikes like this. There are a few things you can do to make it a lot harder in order for thieves to steal your bikes.
Even better if you can use the U-lock around both the frame and rear wheel.
I lived in a complex in mission with underground bike parking. There was a bike stolen from that garage once a month despite my pleas for people to lock them correctly. Cable locks are garbage, take half a second to cut and go. Use a U-lock only with a cable as a secondary lock.
