Long one for context/
We have a local small play park which is on the road of a bus route.
Tonight there were a few small teenage groups behaving lovely (some who I recognise), some dog walkers around and a young child.
I assumed the young child was with the dog walkers until she came into the fenced off play equipment and started to engage with me and my youngest.
They asked me to push them in a swing etc and I asked 'do you live close' to which she replied 'I live there' and pointed at a house. I then asked 'are you allowed to play here alone' and they said 'yes my mum knows, she's in bed but I'm okay'.
We left soon after (7pm) but I said 'I think you should go home' etc repeatedly but she stayed.
When I got home my child indicated that they knew this child was about 5.
Via the teenagers I know parents and the teenager themselves etc we know she got home safe this time (as in a vague report from one of them, after a few of the girls trying to encourage her home it seems she did let herself in). Feedback from them is her mum is of the angry sort.
I'm genuinely worried. She had her uniform on so I know what school she attends (infants!) and I know the office staff and teachers from my kids going there.
AIBU for making a safeguarding type of call tomorrow to the school?
