David Hale, 46, was arrested early Wednesday morning, according to NOPD spokesman Aaron Looney.
Dick had just completed an appearance on the One Eyed Jacks in the French Quarter when he was attacked, according to CNN subsidiary WDSU.
One motive for the attack is unclear.
Lt. Jonathan Fourcade, a spokesperson for the city's emergency services, told CNN that they replied to a call at the location around 2:20 am on Saturday morning and transported a male patient.
Dick was hospitalized as a result of the incident, and a source who knew about the matter told CNN.
A second Dick show at One Eyed Jack's was canceled.
CNN has asked Dick & # 39; s representative for further comments.
