NAX2028 plane dissapeared?

[frompoland]

Hello everyone,
On 15th of March at 22.29 I've noticed a Norwegian airline plane flying from Oslo to Warsaw, which made three circles before Warsaw and finally turned back its way, got lowered and dissapeared. Does anyone know what might have happened?

Not sure, but the aircraft seems to have departed from Warsaw the next day.
