Call for people to report drunken violence in Lincoln
People have been made up to look as if they have black eyes and bloody noses as part of an anti-crime initiative in Lincoln city centre.
The Gauge Your Behaviour campaign used the fake injuries on its staff to show those on a night out the consequences of drink-fuelled trouble.
It is also encouraging revellers to call Crimestoppers if they witness violence on the street.
The multi-agency initiative will run for the next four weekends.
Insp Mark Garthwaite, from Lincolnshire police, said they were tackling an important issue.
"It is one thing to say 'people have been assaulted' but if people witness things and don't do anything about it, then we cannot get to the actual offenders, which would obviously stop them doing it again.
"So the idea is very much publicising what can happen but also how you can report it."
The initiative involves the police, the Crimestoppers charity, fire service, ambulance and town wardens.
