They shared a poster on social media with information on how to help someone who has been spiked, or what to do if you suspect someone has been spiked.
It reads: "Tell a member of staff, bar manager, bouncer. Stay with them and keep them talking. Call and ambulance if their condition deteriorates. Do not let them go home alone. Do not let them leave the venue with someone they don't know. Try and prevent them drinking more alcohol."
They also suggested that if a drink is foggy, has excessive bubbles, sinking ice or changing colour, that is may have been spiked.
