At Feanor Outpost in Edinburgh, each of the 3 blocks has it's own bike storage room, which also houses some utility stuff.
One night last week, all 3 were broken into ( by hoofing the door open ), and *all* the bikes were stolen.
All that was left was the remains of cable locks, cut with bolt cutters it looks like to me.
We had no bikes in storage at the time, so I've not lost anything.
The doors were pretty poorly secured.
They were double doors, with the lock on the RH door, locking into the LH door.
You'd expect the LH door would have a couple of decent bolts top and bottom on the inside.
But no, it was mostly secured with Thoughts and Prayers.
So I reckon even leaning against the mid-point of the 2 doors a bit firmly could have popped it open.
They are looking into securing it better, but I don't know that that means.
