Withholding pay of the employee will not be legally correct.
Did you ask him about any business interests he was having during the interview or during joining processes.
He will say his wife was running the company or family members were running the business.
If he files suit against withholding of pay,then your company may have to pay.

Pay off the dues to the employee and close the matter.
You get all types of people.
Treat it as a learning lesson and move on.
