Deleting Microsoft access database

[Ahmed, Shakir]

I have a Microsoft Access database that I want to delete whether anyone
is using that file. 

The database is already read only mode residing in a server, users are
opening in read only mode. I want to delete that file, I remove read
only check but could not delete that file. 

Getting error message: 
Cannot delete xxx : It is being used by another person or program. 

Any help is highly appreciated.

Thanks
