The above is not intended as legal advice. The response does not constitute the creation of an attorney client relationship as this forum does not provide for a confidential communication.
If he is being held as a juvenile, it will depend on how many points he scores on the release sheet. If it is simple battery, he has probably already been released.
If he is being held as an adult, it could be awhile.
Since he is a juvenile, he can be detained for up to 21 days. After that, if he is charged as an adult, he could face up to a year in jail for a misdemeanor battery or 60 days jail for disorderly conduct. As a juvenile, a lot will depend on what the Dept. of Juvenile Justice recommends.
