A Dane Co. Jail inmate will now face an additional charge after allegedly punching a deputy in the face.

Deputies say 39-year-old Christopher Fox was being escorted from a medical check on Tuesday night when he became agitated. He reportedly was upset about not being allowed to use a staff telephone.

As the escorting deputy was opening a door, authorities say Fox punched him.

The deputy was taken to the emergency room where he was treated and released.

Fox had been booked into jail on February 10th on a Substantial Battery arrest. He'll now face an additional battery charge.
