New York Knicks guard Raymond Felton was arrested on gun charges Tuesday ... after his estranged wife ordered her attorney to bring the player's gun to an NYPD precinct.
According to NYPD, Ariane Raymondo-Felton's attorney handed over the semi-automatic Belgian-made pistol late Monday night.
The following morning, Ray turned himself in to police for questioning.
It's unclear at this point why Felton's wife of just 19 months brought the gun to cops. She filed for divorce last week.
The NBA player was eventually booked for two felonies -- 2nd and 3rd degree possession of a firearm -- as well as 4th degree possession ... a misdemeanor.
Felton went to the Manhattan precinct to deal with the gun trouble ... right after the Knicks lost another heart breaker to the Dallas Mavericks.
