I am concerned about a hedgehog I spotted and posted about yesterday, advice needed.

Hi. I have recently seen a hedgehog in a small grassy area outside an office building. I saw him first last night around 10pm, and today around 8pm when it was still light. He was moving and sniffing, balled up when approached and didn't seem to have any ticks. I am a little concerned as it seems like he is stuck in there, there are high walls around most of the sides, and the only side he can escape from leads directly towards a busy road. It also seems like there's very little water access. The hedgehog did seem healthy but I don't know if it's a good idea to try and move him to a local park instead. Any advice is appreciated.
