"My Neighbor Beats His Wife And Kids Daily, What Can I Do?"

Nairalanders i hail thee.

I'm seeking for help on behalf of my neighbor's wife and her kids, her husband(our landlord) beats his wife and kids everyday(I mean 7 days a week nonstop). This man is usually drunk, I'm really concerned and really pained, as i type now he's beating his wife and has locked them out. I tried some Google searches but it's not helping. Please this woman and her kids needs help, but hat can be done.

Thanks
