Let's just cut some holes in it

While my bathroom leak seems to have been fixed, it kept dripping from the ceiling on the ground floor in the corridor. And if anything, it kept getting worse with water running down the wall. When I checked with the concierge, it turned out that the flat below me also had a leak. And that there were some flats they hadn't been able to check as tenants weren't in. The manager clearly hadn't taken this very seriously when it first started a few weeks ago...

Anyhow, at the end of the week, I came home to this:

no worries: that's in the corridor, not inside my flat!!!

No idea what they did or why they did it, but making holes in the ceiling seems to have done the trick!
