Wildenstein was first arrested for allegedly clawing Klein across the face and slashing him with scissors in a fight. Klein claimed he was forced to put Wildenstein into a walk-in closet to stop her attack him before the police arrived. Later that month, Daily Mail obtained a video showing her hitting him with a tray while he urged her to calm down.

However, just a few days later, Klein was arrested on charges of grabbing and pushing Wildenstein to the ground when he returned to the apartment to collect his belongings. Klein's representative told People magazine he was arrested "after patently false allegations were made to the NYPD by Mrs Wildenstein alleging a physical altercation with Mr Klein" and that they are fully cooperating with authorities to "clear Mr Klein of these allegations and expect this matter to be dismissed shortly."

Klein still awaits to hear whether he has been charged with assault, as well as robbery, grand larceny and criminal mischief, according to the Daily Mail citing a police source, after Klein also took an iPhone, another mobile phone, a Swiss ID and a credit card without Wildenstein's permission.
