Neighbors Bees Attack! Help!?

[Shayne Fee]

The neighbor of one of my homes has bees in their yard. Not sure if it's a hive in a tree or an actual bee box but the bees are stinging my tenants and tenants dog! 

I have talked to the owner and he says it's the other neighbor (it's not) then ended the discussion abruptly. 

What should I do???

I would suggesting calling the cops to see if they can setup a sting operation...
