A woman who was arrested in relation to offences connected to saline bags being tampered with at the Cumberland Infirmary has been released under investigation.

The 24-year-old woman, who lives in Wigton, was arrested last Friday and released the following day on suspicion of attempting to pervert the course of justice and appearing to contaminate goods.

A six-month police investigation was launched after hospital workers raised the alarm on January 4.

Staff reported that saline solution bags in the infirmary appeared to have been tampered with.

Hospital bosses have always stressed that no patients were adversely affected.

Saline is commonly used to mix drugs and is routinely administered to patients via a drip.

Following the scare, all saline bags were removed from the hospital and replaced as a precaution.

Police enquiries are ongoing and officers will continue to work closely with the North Cumbria University Hospitals Trust.

Anyone with information is asked to contact police on 101, or by email on 101@cumbria.police.uk.

Alternatively, you can contact Crimestoppers, anonymously, on 0800 555 111.
