Jackson alleges he was roughly treated and left with a bruised arm and dislocated shoulder. The Sheriff's Department previously said Jackson "was treated with courtesy and professionalism throughout the arrest and booking process."
"Some of the points will be addressed a little more specifically" during a news conference Wednesday with Santa Barbara County Sheriff Jim Anderson, a jail spokesman said Tuesday.
Jackson, 45, is charged with seven counts of performing lewd or lascivious acts on a child under 14 and two counts of administering an intoxicating agent, reportedly wine.
Meanwhile, all warrants and affidavits in the case will be sealed under an agreement reached by prosecutors and Jackson's defense team. The court order said the documents should remain sealed until the scheduled Jan. 16 arraignment.
In a CBS "60 Minutes" interview broadcast Sunday, Jackson said he was "manhandled" after he surrendered Nov. 20.
"My shoulder is dislocated, literally. It's hurting very badly. I'm in pain all the time," Jackson said. "It's very swollen. ... It keeps me from sleeping at night."
He displayed what he said was a bruise on his right arm from the treatment, and said his shoulder was dislocated, although news videos showed him waving to fans after leaving the jail.
Jackson said he was locked in a restroom for 45 minutes after he asked to use the facilities. He said the room was smelly because of feces thrown all over.
Jackson has not filed a formal complaint.
Chief Deputy Fred Olguin, who oversees the jail and was present at Jackson's booking, denied the singer was mistreated, the Santa Barbara News-Press reported Tuesday.
"I don't run my jail that way, and I take a lot of pride in how the jail is run," he said. "I don't understand where he comes off with that."
