If my husband was jailed 72 hour hold after his PO did a home visit and he admitted he would not give a clean UA, will he be released after 72 hour?

72 hour hold doesn't sound right unless he was taken to detox or the psych ward. Instead, was he arrested for a probation violation? If so, then he would normally see a judge sooner, but depends on when the arrest took place. He doesn't have the absolute right to bail if he?s already on probation. So the judge could order him to be held without bail. Get a lawyer hired for him.
