An absconding report against an employee for not reporting to work for 7 days

Dear sir/madam,

One of our employees has not reported to work for 7 consecutive days and we are unsure of any whereabouts.

Can we file an absconding report?

What are the fees and implications for the employer?

Do we need to pay WPS and gratuity if the employee returns?

The employee has been working with the company for over a year now.
