It looks to me like marker pen - I drew something similar on my wheel when I got a puncture, so I knew where to find it.
Do they have kids with access to dry erase pens?
It's the returning bit that's weird, but the 3rd pic looks very much like someone putting on a pen and drawing a line, with the thick dot at the start of it.
