U.S. basketball ace Royce White is at the centre of a police probe over claims he assaulted his ex-girlfriend, according to a new report.

Officers received details of model Tania Mehra getting a cut above her eye during an incident at the sportsman's home in Houston, Texas in June (13), but she told cops she had fallen over.

Now Mehra has filed a follow-up report insisting the injury was sustained when Royce assaulted her during an argument, according to Tmz.com.

An unnamed officer tells the website, "The victim said she had lied earlier because the suspect played for the Nba (National Basketball Association) and did not want the incident to damage his career."
