Police in Newport Beach announced they have closed an investigation into allegations that Josh Giddey had an improper relationship with an underage girl and will not pursue charges. 

"After a thorough and exhaustive examination, we have completed our investigation into information that was circulating on social media involving Josh Giddey," the statement read. "Our detectives have reviewed all of the available information and were unable to corroborate any criminal activity related to Mr. Giddey."

Adam Silver said in early December that the league office's investigation would "take a back seat" to the Newport Beach police's process.

"Generally, we will work with law enforcement to the extent they will share with us the information they have," Silver said during his Las Vegas news conference before the NBA's in-season tournament final. "We can learn from that. We gather whatever information is available to us, in working alongside a police department in this case, or a D.A. As long as they say that we are not interfering with their investigation, we do what we can at the same time. But generally, we fall in behind any investigation and then go from there."

Giddey has been routinely booed in road games since the allegations surfaced.
