u/ReturnEmbarrassed298

Just looking for some advice/answers really, my partners grandad was viciously attacked outside a pub completely unprovoked he's in he's late 80s, the 22 year old scum who did this bottled him multiple time but after being arrested he's been let out and back in the area ( the pub is bang opposite grandads house) how has he been let out already the next day? I'm not really sure how it works but the 22yo was heard saying " thats where the cunt lives who got me arrested " 🤦‍♂️ will he be on watch? Is he likely on bail for now? I've no clue but bit worrying how he's in the area already and clearly very violent.
