Medical student Sarah Houston, 23, died after taking a slimming drug which contained the dangerous fat burning drug DNP.

On the anniversary of Sarah's death, her parents, Geoff and Gina Houston say there need to be tighter regulations as these pills continue to claim lives in the UK.

There have been three further deaths relating to this drug since Sarah died and her parents want to send a message to those who take the pills that they are incredibly dangerous.
