This presents a problem, as while some are involved in criminal activity, like drugs and theft, many are a danger only to themselves and need help to exist or get their life back.
The City Centre Response Team has a role to play on both counts, and their job is to make the city centre safer for everyone.
The statistics highlighted by the Evening Times Crime on Your Street series show that crime in the city centre is falling, and that is down to a number of factors and partnerships working to provide the police with assistance is one such contributing factor.
Police officers can't be everywhere at once, and the more intelligence that can be gathered from other agencies and the public, the better they can respond to where the problems are and help prevent crime and anti-social behaviour.
Of equal importance is identifying those living on the streets and helping put them in touch with support services to give them the help the need.
The more eyes and ears on the streets identifying problems, the better chance we have of a safer city centre for everyone.
