A 16-year-old boy has been stabbed in the arm in an "outrageous" unprovoked attack as he sat in a car in a Glasgow street.

Detectives have appealed for help to trace the suspects in the Wellhouse Road incident, who were in a blue Peugeot 208 with yellow and blue wavy stripes. The car was being driven by a woman in her 20s with blonde dip-dyed hair. The other suspects were two white men in their 20s, and a young boy aged around 10 or 11.
