Detectives are investigating after two more women have reported being spiked by injection when they were out in Brighton on Tuesday night and early hours of Wednesday morning.

Officers are increasing patrols as part of their continued work policing the night-time economy, and will continue working closely with partners and licensed premises on initiatives to help keep their patrons safe.

Students are planning to boycott nightclubs next week as part of nationwide protests, with more than 30 universities taking part in the campaign in a bid to force venues to increase safety measures.

Following reports of spiking by needles in Nottingham, a petition calling for it to be a ‘legal requirement’ for nightclubs to ‘thoroughly’ search customers upon arrival has been signed by more than 130,000 people.

The Girls’ Night In campaign will spread across 43 university towns and cities over the next fortnight. It comes in response to a reported rise in drinks being ‘spiked’ and a new alarming trend of girls being injected unknowingly with drugs.

Those taking part in the boycott will stay at home on a designated night to raise awareness of the attacks and encourage venues to improve security.

New figures have also emerged showing 15 per cent of females, seven per cent of males and 17 per cent of those identifying as other have had their drink spiked, according to a snap poll by The Alcohol Education Trust.
