f(x) Krystal in shock after being assaulted at airport

A photo is quickly going viral showing f(x) member Krystal being grabbed from behind by what appears to be a fan without warning. 

In the photo, Krystal clearly looks shocked and displeased at the inappropriate physical act, as she has no idea who is approaching her or grabbing her. She looks to attempt to free herself from the fans grasp, but has trouble due to being held on so tight.

f(x) stylist quickly realizes what is happening and also looks extremely confused and shocked, leaning towards to the perpetrator in what appears to be an attempt to stop her.

Stay tuned for more on this developing story.
