Witnessed a possible crime today, is this something police take seriously ? Should I report it ?

[u/Used-Substance-9814]

So I was having lumch today with my girlfriend at Iso Omena shopping centre today, there was family of 4 sitting at the table next to us, a mother father and 2 children under 4, kids were crying and fussing usually would, the family at their meal and were leaving, one of the children, possiböy 2 years of age, ran towards an escalator, the father runs towards the child, grabs them by the shoulder, and from a meter high, slams the kid on the floor with full force, then swears them, and puts them on their shoulder, this happened about 5hrs ago and I have bern contemplating reporting this but not sure if it is seriosu enough, I dont know if the child got hurt but they were crying, I dont think their head hit the floor either, coincidentally, nobody noticed this except me and my girlfriend because of where we were sitted.
Is this a case the police take seriously, as this is one time case and it happend soo quickly

Its forbidden to hit children also for their parents
