He is probably trying to humiliate you by having you come in and at the same time take all your access. You should go in however if he crosses the line escalate the issue politely to his boss asking what you should do when you have resigned and he wants you to come in but have nothing for you to do. Remember its a two way street. May be your are young or don't know what to do and he senses that and he is just taking advantage of your situation. I would also talk to a lawyer and see what your options are. At the end don't be afraid to act (polite but strong) otherwise the regret will stay with you. Good luck
