I noticed several news articles reporting that an unnamed sports star has been arrested for a serious crime. All the articles mention that the accused could not be named "for legal reasons". I could assume that the news organizations do not know the identity of the accused, but the articles are unclear and in my opinion, make it seem like they know the persons identity, but are prohibited from disclosing it.

I have never heard of this in the United States, and I was curious to know what laws or "legal reasons" that would prohibit a news organization from releasing the identity of a suspect if it is known. I understand that making unknown or false statements like "person A is a rapist" could be libelous if untrue, but just reporting that "person A was arrested for a serious crime" would be OK as long as this is a true fact and actually happened.
What "legal reasons" would prevent a news organization from releasing the identity of the accused?
