Police have issued a warning after two teenagers fell seriously ill in Sheffield after taking small green pills which made them aggressive, writes Graham Walker.
The two, aged 16 and 17, were taken to the Northern General Hospital this morning after taking the tablets.
It is believed the teenagers took the drugs at an event last night, possibly on Effingham Road in the Attercliffe area of the city.
A South Yorkshire Police spokeswoman said they were taken to hospital after displaying aggressive behaviour.
A 17-year-old boy has been arrested on suspicion of supplying the drugs and is in police custody.
Police are warning people not to take the unknown green pills and to seek urgent medical advice if already consumed.
Anyone with information about these pills is urged to call South Yorkshire Police on 101.
