Squatters are using my REO at night

[Bienes Raices]

Yesterday I found fresh human waste in the toilet at the REO I have under contract. Today I was there with the mold specialist and we found food remnants and some drug paraphernalia.

House is owned by a mega-bank and my agent is trying to get in touch w/ asset manager/listing agent to have them call the police, etc...

This house is a good deal & I don't want to back out just because of this. But am I allowed to secure a property that is not mine yet? Sliding glass door is broken, screens on enclosure have been cut and front window is broken. If the bank doesn't take action, what would you do in this situation?

Technically my inspection pd. hasn't begun yet--we are waiting on changes to addendum, but they have it on Pending for me.
