Narrative:

With first officer flying at 7;000 AGL on the korry arrival we encountered what appeared to be wake turbulence which violently upset control of the aircraft. I immediately advised ATC we were in wake turbulence and were climbing a couple of hundred feet. This was acknowledged by ATC. The first officer got us out of the wake and we continued onto lga without further incident.
