Theft of Credit Card Numbers from Merchant

Restaurant employee or outsider (cleaning crew perhaps)stole the credit card information from patrons of restaurant. Over $15,000 charges were made against the cards. The credit card company has requested reimbursement from restaurant. Is this covered under the employee dishonesty coverage or another coverage under crime policy, and what if an outsider committed the theft? If not, would general liability policy respond if restaurant was sued by credit card company?
