Few details are available at this time, probably due to the suspect still being in a tree. But according to the report, police and firefighters are on the scene, and hostage negotiators—which I assume means people who would ordinarily be negotiating to free hostages, but in this case are trying to talk a guy out of a tree—have so far been unsuccessful.
The report says the man is “surviving” on “food and glucose packs” the officers have given him, although 48 hours isn’t enough time to be at risk from starvation, and maybe if they hadn’t fed him he’d have come down by now. As for his other needs, the report claims he has been “peeing in the tree” but that almost certainly means “peeing out of the tree,” which is surely making the hostage negotiators’ task even more unpleasant.
