Police have issued warnings regarding green "Rock Star" pills, which are emblazoned with a star motif after the death of a teenager in Liverpool.
A drug dubbed "Rock Star" sparked a series of police warnings in Lanarkshire, Scotland, in March after seven people were hospitalised and one died after allegedly taking the tablets which were being sold as Ecstasy.
The Scottish pills were described as yellow or red and were also said to have carried a star logo.
Officers from Strathclyde Police said at the time that while the exact contents were unknown, they could contain a cocktail of different substances.
