Operation Parkside, in collaboration with partners including Arun and Chichester District Councils and British Transport Police, focused on a multi-agency effort at local train stations last Monday.
Officers and staff engaged with the community, businesses, and young people in the village and city centre to offer reassurance and gather feedback.
Chief Inspector Will Keating-Jones, District Commander for Chichester and Arun, said: “We were able to combine both Operation Parkside and Operation Precinct on Monday to show that Sussex Police take a zero-tolerance approach to crime and disorder in our communities.
"It also enables us to provide reassurance and engagement opportunities for residents, with the aim of identifying criminality and holding offenders to account for their actions.
“Throughout this year, our teams have worked extremely hard to tackle crime and ASB in Barnham, Yapton and Chichester and this multi-agency partnership day shows the measures we are taking together to keep crime and anti-social behaviour at bay.
“It was a huge success as we were able to speak to, and engage with, a number of residents, commuters, school children and businesses on the day.
“This work does not just stop at Chichester and Barnham, we will look to host multi-agency days of action across West Sussex to combat serious violence, anti-social behaviour and all crime types reported near the rail network.”
