A campaign to counter terrorism has been launched.

Police across Sussex and Surrey are supporting the national campaign to raise awareness and encourage people to be vigilant.

Five key areas are being highlighted this week: crowded places; transport hubs; preventing violent extremism; terrorist financing and the tools terrorists need to operate.

Police will be at various locations including Gatwick train station; Clacket Lane service station; University of Surrey; money bureaus in Crawley and Gatwick; as well as gyms and gun clubs in an attempt to inform people how to spot terrorist activity and combat it.
