Forty people were treated by paramedics after pepper spray was released inside a nightclub.

Revellers complained of shortness of breath and stinging eyes following the incident at Cameo in Bournemouth in the early hours of Saturday, Dorset Police said.

One person was taken to hospital as a precaution.

Officers were called to the club in Fir Vale Road at 2am and management evacuated the venue, which was filled with up to 2,200 clubbers on the night, Cameo said.

Pictures on social media showed crowds gathered in the street outside as police and ambulances attended.

Cameo posted a statement on Facebook on Saturday afternoon which read: “Last night there was an incident in the main room at the club where a small canister of pepper spray was set off on the dance floor.

“This was a silly, pointless act and we hope that those of our customers who were caught up in it are feeling better today and are now fully recovered.

“Customer safety is of paramount importance to us, we utilise a combination of searching customers, metal arches and wands – all of which are above and beyond what our licence asks us to do.

“It is likely that the canister which was set off last night was in a small plastic container.”

The club will open for business as usual on Saturday night.

Josh Wilde, 20, told the Press Association Cameo had recently introduced thorough searches on the door with airport-style scanners, but he said only some clubbers had to go through them.

The third-year journalism student said: “It had the most security at a club I’ve ever seen outside central London. There were hundreds of people queuing to get in, it was absolutely packed, I queued for at least an hour.

“I initially thought someone had got on to the stage because security were running around the main room, but then a firefighter rushed past in full gear so I knew it must be something more serious.”

A Dorset Police spokeswoman said: “Following a decision by management of the premises to evacuate, around 40 people were treated by the ambulance service for minor effects, such as shortness of breath and stinging eyes.

“One person was taken to hospital as a precaution.”

The force said officers had searched the nightclub and found no evidence of any chemical or noxious substance which posed a continuing risk to the public.

Rapper Yungen had been performing at the club as part of an event to mark university freshers’ week.

He later said on Twitter: “Everyone that just come to see me in Bournemouth as I’m sure all of you could see the police shut off my mic without saying anything mid performance because apparently someone sprayed pepper spray … I hope everyone’s safe”.
