Teenager dies after fears her drink was spiked A statement from Merseyside Police said: "A 16-year-old man from the L5 area has also been arrested on suspicion of supplying controlled substances as part of the ongoing investigation. He is currently in police custody and being questioned by officers. Detective Superintendent Tim Keelan of Merseyside Police said: "At this stage it is too early to draw conclusions about the cause of death and it is unhelpful to speculate. The implication that this may be drug related is just one of the lines of inquiry that our comprehensive investigation is looking at. That said, I would like to take this opportunity to warn people about the dangers of taking illegal substances. The effects of drugs are not always immediately apparent or can be delayed. This can sometimes result in people taking more in order to speed up the effects. This can have devastating results, one of which can be death. The force had warned of a potentially killer new drug on the streets in the form of pink pills, known as pink ecstasy, Dr Death or Pink McDonalds - because the pills are embossed with an M. The warning was issued following the sudden deaths of two men in 24 hours in Cambridgeshire earlier this week. A man also died in similar circumstances in Bournemouth, Dorset, on May 21. Emergency workers were called to Miss Farley's home in the West Derby area of the city during the early hours of yesterday morning. Reports suggested she had spent the evening at a social club party before being taken ill, and may have had her drink spiked. More than 4,500 Facebook users have viewed a tribute page set up in her memory.
