Child abuse (16 yrs old)

Good day, im looking for some advice not for me but for my friend in the philippines, currently im here in Riyadh for work, the story like this:

My friend is about 20yrs old and yung naka-away niy is about 16 yrs old. then yung family nung 16yrs old nag sampa ng reklamo ng child abuse with medical certificate ang kaso po yung 16yrs old po na yun ang nanguna kumbaga self defense lang ang ginawa ng friend ko. Kasi sa isang eskinata magsasalubong sila, then yung 16yrs old na girl sinapak nya yung friend ko ang friend ko that time karga nya anak nya, alangan naman pong magpasapak na lng yung friend ko, andami pong witness na magpapatunay kunga ano po talaga ang nangyari, then what i hear po, nakatanggap po ng subpoena ang friend ko. Hindi na po sila dumaan sa lupon diretso napo filling of case pwede po ba yun? then every now and then laging nagpaparinig ang family ng 16yrs old na makukulong daw ang friend. i need some advise kasi po till now la pa abogado friend ko..

he should be focusing on preparing a counter affidavit. the best he can do is just tell the truth of what happened.
