Can my ex-boss keep my next paycheck?

I recently quit my job because I felt I was being treated unfairly in the workplace. I did not give 2 weeks notice, but instead just quit. My boss informed me through text that I owed him 50 dollars and if I didn't give him the money owed, he would withhold my next paycheck. He then said that he could do it because I didn't give 2 weeks notice. I don't think he can do this, and I don't remember signing any contract or anything like that, so I'm pretty sure there isn't any way that he can keep it. Also, couldn't I get him in trouble for bribery?
