Is this water from the flat above causing ceiling staining dots?

Hi guys I'm hoping you can help me. The flat above has previously had water leaks, although not directly above the room in question. Is the dotting mold, water staining or something else? I'd obviously like to ask the flat owner upstairs to pay if this is caused by water leaking. http://ift.tt/2aJ7MwE http://ift.tt/2b0SH8r

The marks are more brown grey in real life
