A post-mortem examination has failed to establish a cause of death for the fitness fanatic Epsom student who died hours after allegedly praising deadly body-building pills on Facebook. 

Sarmad Alladin, 18, who was an art and design student at the University for the Creative Arts (UCA) in Epsom, died suddenly on February 13.

The son of an Indian millionaire, originally from Hyderabad, Mr Alladin praised fat-burning tablets called DNP on Facebook just hours before his death, according to national media reports. 

Six hours after Mr Alladin's death UCA had issued a warning against the use of body-building and weight-loss drugs via its Student Union's website.

But a spokesman for Surrey Police said a post-mortem examination carried out on Friday, February 22, did not establish a cause of death and that further toxicology tests were being carried out.

He said: "Police are investigating the circumstances surrounding the incident, but at this stage the death is being treated as unexplained and there is no suggestion of any third party involvement.

"An inquest into the death has been opened and adjourned."

Conflicting tribute messages, as to whether Mr Alladin would have used body-building tablets, have been left on a Facebook page dedicated to his memory. 

Hannan Razvi wrote: "Our friend's image is being exploited by the media.  We are sure that he did not die due to overdose of DNP.

"Please do not believe whatever the media says.  The media has no proof about how Sarmad Alladin died and the cause of death is still unknown.  Please repsect his departed soul."

Ingod Email added: "Oh god.  So young.  This happens when you don't really like your body.  I think he didn't try a good method to lose weight."

Nawab Alladin said: "Whatever notion is going on in the media is portraying him to be a spoilt brat, but the actual truth is he was a very down-to-earth person and he had no air about his wealth."
