POLICE have issued a warning after a teenage girl died after taking ecstasy.

Officers investigating the death of the 17-year-old girl are urging anyone who may have taken a form of ecstasy known as 'MasterCard' to urgently seek medical attention.

Police were called to the Victoria Warehouse, on Trafford Wharf Road, in Trafford - shortly after 5am on bank holiday Monday - after a teenage girl suffered an adverse reaction after allegedly taking one 'MasterCard' ecstasy pill while on a night out.

She died in hospital a short time later.

Police are now concerned about any others who may have taken the pills and want to encourage anyone who may have taken the drug to urgently seek medical attention.

Detective Inspector Helen Bell, from GMP’s Trafford Division, said: “This is a tragic situation, the death of a young person is always devastating, but in these circumstances, it is all the more heart-breaking. My thoughts are with her family and friends at this time.

“Sadly we know it is very unlikely that the girl was the only person to have taken this drug last night.

“We are appealing to anyone who may have taken this form of ecstasy, known as 'MasterCard' to get checked out urgently. Even if you took it some hours ago, this pill will still be in your system and could be seriously harming your health.

“Anyone with any information about what happened or where this drug may have come from is asked to contact police as soon as possible.”

From 9pm on Sunday until 6am on Monday, Victoria Warehouse hosted the Don’t Let Daddy Know clubnight. 

Up to 5,000 clubbers were expected to descend on the venue to enjoy Dutch dance music DJs at the bank holiday event. 

Anyone with information should call police on 0161 8567662 , 101 or the independent charity Crimestoppers anonymously on 0800 555 111.
