If you had any idea about the candidate's profile of having owing a business of his own, you should not have given him an employment. If required, you should have included a clause in the appointment order to the effect that he should not do any business of profit while in employment. Normally, an establishment having a certified standing orders will have a provision to this effect. Now, since he has put his papers, leave him. You can not hold his salary and other benefits unless you have a specific clause to do so as described above. This is because, the salary is a remuneration due to him which is payable in consideration for the work you have extracted from the employee and by holding it you may be inviting troubles. Therefore, settle him.
