A NEW police poster campaign has been launched in Okehampton — in both English and Polish. The posters, which will be displayed in pubs around the town, are targeted against under-age drinking and anti-social behaviour. 'We're making sure we target as many people as possible — making sure they're given the same warning,' said PC Rupert Dodge, who is heading the campaign. Polish is now the second language in Devon and Cornwall. In English, the poster reads: '18? Prove it. If you look under 21 you will be asked for photo ID'. * Poster spells it out in Polish
