West end bike thief gang

What will they do? Last time I said to a copper there's two kids around the corner nicking a scooter they got on their radios to report it dilly dallying and the culprits were gone along with the scooter

I don't mean try to get them to nick them on the spot. You can give them information that can enable them to focus their detective work and prepare to catch them. The police are definitely interested in gangs.
