Contact home immediately, and continue to contact parents/guardians when this type of behaviour occurs. In some cases, there will not be any support from home, but it shows the student that home and school are connected, and that the behaviour will not be tolerated. Get the admin team on your side by talking to them about your concerns. Be firm with your rules and provide consequences.
There is no magic answer, as some students will just continue to behave poorly, but these are some strategies you could use. Good luck!
