A 15-year-old boy has been arrested in connection with the supply of drugs in West Lothian.
The teenager has been charged with supplying drugs in the East Calder area on Sunday.
Meanwhile, police in the same area are continuing to investigate the death of 15-year-old Dione Melville at the weekend.
The teenager died and two other girls were taken to hospital as a precaution after emergency services were called to an address in East Calder on Sunday morning.
Officers are currently treating the death as "unexplained''.
Lisa Grubb, West Calder High School acting head teacher, said: "Dione was a popular girl and this is clearly a very upsetting time for her friends and family.
"Dione was an ambitious young lady who had plans to work in hairdressing and in the beauty industry after leaving school in the summer. She was very focused on her future and the thoughts of the entire school community are with Dione's family and friends at this incredibly sad time.''
Dozens of tributes have also been left on social media by friends of the schoolgirl, who was from West Calder.
One said: "Rest in paradise, my beautiful girl. You didn't deserve to get taken away from us. Shine bright, fly high and sleep tight babe. I love and miss you forever and ever my girl.''
