When is Going Far Too Far? Primary school in Enugu allegedly arrests 4 to 7 years old pupils for refusing to do their assignments

Saw this on instagram and i am shocked beyond words. Should this be acceptable under any guise? Even if the police van didnt leave the school premises?

I just want to tell myself this may not be real or is it? Drop comments if you know more of what happened please. Do you think this was okay?
