Having problems with my brother

Hi everyone!Would like to ask if pwede mo ba ipakulong brother mo if he constantly disturb ung katahimikan ng bahay namin.Sorry sa words.Dont know how to say it right.Minsan na kasi kami nag-away and he tried and threatened to punch me.Now,pag di nya nakukuha ang gusto nya or napapagalitan sya he keeps on slamming doors kahit na tulog na lahat,maski 1 am na.Nasa 3rd floor room nya then he always make noises para maagitate kami.pati baby nagigising.He punches things.Separated parents namin,mom nalang namin nagsusuport sa amin.He's 21 years old ,by the way.I know for sure na medyo may kababawan problema ko pero para kasi gusto na syang patayin sa ugali nya.Bago pa ko makagawa ng di mabuti would like to ask any legal advice para mapatigil lang sya.Kinausap na sya ng maayos.pero mas lalong lumala.

i don't know if it will make it worse still, but your remedy is to file a complaint at the bgy.
