An 18-year-old university student has died after taking lethal bodybuilding pills in a bid to lose weight.
Sarmad Alladin collapsed and died in the early hours of Wednesday morning.
It is believed that the 18 year old was using a drug called dinitrophenol, more commonly known as DNP.
Police are investigating the death which is being treated as unexplained.
A spokesman said: "Surrey Police received reports of the sudden death of an 18-year-old man at Epsom General Hospital on Wednesday February 13.
"Police are investigating the circumstances surrounding the incident. At this stage the death is being treated as unexplained but there is nothing to suggest any third party involvement.
"Officers are liaising with coroner's office and a post-mortem will be held in due course."
Mr Alladin, the son of an Indian millionaire, was staying in University accommodation in Epsom while studying for an art and design diploma at the University for Creative Arts.
Since the death of Mr Alladin, the staff at UCA has warned its students against using weight loss drugs.
A spokeswoman said: "We acted on the advice of police and put out a warning to all our students about the dangers of bodybuilding/weight-loss drugs. This was done as a precautionary measure".
"UCA has a close working relationship with the police and health authorities local to our campuses. We are proactive in responding to any issues that impact on student welfare – even if the risks are slight."
DNP was used in slimming pills in the the US during the early 1930s but was banned in 1938 due to the dangerous side effects that can be caused by taking it.
