AN investigation into a five-year-old girl 'getting into difficulty' at a swimming lesson has concluded the incident was 'accidental'.

Eyewitnesses said they saw Lexi Jackson's body 'convulsing and jerking' under water while parents screamed for someone to 'get her out' at Hyndburn Leisure Centre last Thursday.

The five-year-old was rescued by a lifeguard at the pool side and given CPR before being taken to Royal Blackburn Hospital, where she has since made a full recovery.

Police have confirmed investigations have now ended.

A Hyndburn Leisure Centre spokesman said: "The safety of our customers is paramount to us.

"Firstly, we would like to make it clear that our main concerns are with the child and her family.

"We are delighted to hear that she has been released from hospital and made a full recovery.

"We hope people understand that we were unable to respond whilst an active police investigation was taking place.

"We were informed that the police investigation had concluded and the police will not be pursuing any criminal investigation.

"An ambulance was called immediately whilst staff performed CPR at pool side.

"During the rescue, a customer identified herself as an accident and emergency nurse and offered assistance with CPR, which of course we accepted.

"The child was revived and was conscious when paramedics arrived.

"CCTV shows that there was one minute 10 seconds between the first child in the group entering the pool to start an activity, and the girl being rescued by a lifeguard.

"Swimming lessons are delivered in accordance with Swim England's National Plan for Teaching Swimming.

"All our swimming instructors go through in depth training to receive their qualifications.

"Lifeguards are Royal Life Saving Society qualified and trained in first aid and our ratio of instructors and lifeguards complies with industry standards.

"We will continue with our internal investigation and will share the findings in due course."

Det Sgt Kate Kennedy, of Lancashire Police, said: "We have conducted a full investigation and will be taking no further action.

"We believe the incident was purely accidental and are thankful the girl involved has gone on to make a full recovery, helped by the quick-thinking actions of leisure centre staff and medics.

"Hyndburn Borough Council is aware and the matter has been referred to the Health and Safety Executive."
