Hello Birenbi,
Further to what Harsh mentioned--about the Police & Medical Reports--pl get the details of the accident from the employee.
Did he/she have any fracture or any such physical conditions that form the basis of the paid holidays? You can then ask for the X-Ray/CT Scan/etc Reports to corroborate what the Medical Reports mention [cross-check with your company Doctor].
When Medical Reports can be 'arranged' all over the country, depending on JUST those Reports may not be wise.
A few months back, we insisted on a case for the photos to be sent when the individual said he had an accident & suffered a fracture of hand & was on plaster/sling--in addition to the Medical Reports & X-Rays.
Rgds,
TS
