A police investigation is underway after a 15-year-old boy was hit in the face with a bottle and kicked during an attack by a gang of teenagers on Buckie Road in Mayfield, Midlothian, on Friday night.
He was taken to Edinburgh Royal Infirmary with a serious facial injury.
Detective Constable Lynn Myles said: “This was a brutal and frightening attack, which has left a 15-year-old with significant injuries.
“We are eager to trace the youths responsible for this incident, particularly the male who used a bottle as part of the assault.
“I would ask anyone who saw this incident, or recognises the description of the suspect, to contact us as soon as possible.
“I would especially appeal anyone who may have filmed this incident on a mobile device to get in touch with us and let us see this evidence.”
