Three people have been charged under the Misuse of Drugs Act following the death of a 16-year-old girl in Midlothian.

Shellie Callaghan reportedly fell ill at a house party in Newtongrange and was taken to Edinburgh Royal Infirmary on Saturday October 15.

A 42-year-old woman and two other females, aged 16 and 17, were arrested on Monday after properties were searched in Newtongrange, Gorebridge and Easthouses.

Police Scotland issued a drugs warning following the teenager's death and were following a line of inquiry that she may have had access to "ecstasy-type tablets" known as "red bugatti veyron" and "purple ninja turtle".

Community Inspector Michelle Ritchie said: "We are continuing our inquiries to establish the circumstances surrounding the tragic death of 16-year-old Shellie Callaghan at the weekend.

"Whether she had access to ecstasy-type tablets remains a line of inquiry we are following, and we continue to urge anyone who has taken such tablets to seek medical attention.

"Today officers executed warrants across Midlothian in connection with her death and seized a quantity of drugs and associated paraphernalia.

"Drug dealing, their misuse and the criminality and anti-social behaviour that is associated with this is a priority for police in the Lothians and Scottish Borders.

"Information from the community is vital to enable us to build a profile of issues and respond.

"I would appeal to anyone with such information to contact police on 101 or Crimestoppers anonymously on 0800 555 111 so that we can take action."

The three are expected to appear in Edinburgh Sheriff Court on Tuesday.
