The Newport Beach Police Department said that its detectives are conducting an investigation into an accusation that Oklahoma City Thunder guard Josh Giddey had an improper relationship with an underage girl.

In a since-deleted post, an anonymous social media user last week said a girl who is seen with Giddey in videos and photographs was a high school junior at the time. The social media account has since been deactivated.

Giddey, an Australian, turned 21 in October.

The Newport Beach Police said in a news release that it is “actively seeking additional information related to these allegations and pursuing all leads and evidence to obtain the facts of the case.”

cuban agrees to sell majority stake in mavs >> Dallas Mavericks owner Mark Cuban has entered into an agreement to sell a majority stake in the NBA franchise to the family that runs the Las Vegas Sands casino company, it was announced Wednesday. The deal could be completed in the coming weeks.

The agreement would be in the valuation range of $3.5 billion, according to a person who spoke to The Associated Press on condition of anonymity because that detail was not being made public. Cuban would retain control of basketball operations in the deal.

The company controlled by Miriam Adelson, widow of casino magnate Sheldon Adelson, announced earlier Tuesday it was selling $2 billion of her shares to buy an unspecified professional sports team. It revealed Wednesday that the team was the Mavericks.

The 65-year-old Cuban, who just announced he was leaving the popular business TV program “Shark Tank” after a 16th season next year, rose to fame quickly after buying the Mavericks in 2000.
