Casino markers taken out on company checking account

I'm looking for someone that may have knowledge with this. Long story short I just got a call from my bank that there were 3 casino markers trying to charge a company checking account. The person who did this is a partner of the business with a small ownership of 5% with markers totaling $100,000 which his 5% cannot cover. Is this person liable for the debts or will the company be liable. This account was opened with no blank check. Just the numbers for the bank account was given to the casino along with his ID and they approved these markers

Edit: in the partnership agreement it says no partner shall take funds from the company for personal use unless a written authorization from all partners is granted.

I'm hoping that will cover me from paying these. I told the bank to decline them and have opened a new checking account for the business as I'm afraid more markers will be coming in.

I spoke with MGM and I was told casino markers can only be taken out on a business account if it's a sole proprietorship. Either MGM didn't ask or he lied.

I would seek legal counsel which I am not, but I would think this would be similar to embezzlement. I also would think that if this person has authorizations to write checks then they could go through. Luckily it sounds like the bank called you and you prevented them from going through.
