Police have cordoned off a nightspot where two teenagers are believed to have been partying before their deaths in a feared double drug tragedy.
Officers were spotted speaking to workers around the SWG3 venue in Glasgow this afternoon.
A police car and a patrol car were parked in the grounds of Yorkhill, where Saturday’s 13-hour rave took place.
The site is understood to remain closed with cordons blocking Eastvale Place while police conduct their investigation.
The two clubbers – both aged 18 – died after attending the event with Ibiza DJ Ben Hemsley.
One collapsed at the venue and was taken to nearby Queen Elizabeth University Hospital, where he died shortly thereafter.
The second man was found exhausted at Croy railway station in Lanarkshire.
He was taken to Monklands University Hospital in Airdrie but could not be revived.
Police are investigating whether the deaths are drug-related.
A source said: “It’s every parent’s worst nightmare – their kids are having a great time and not coming home.”

“These deaths are very similar in nature and both men were in the same place at the same time.
“It’s imperative to make more connections, even if the toxic substances come from the same person.”
The sold-out event, featuring Ibiza DJ Ben Hemsley, started at 2pm at Galvanisers Yard, part of the complex.
After his performance ended at 10pm, an afterparty was held indoors until 3am.
A police spokesman said: “The investigation to fully clarify the circumstances is ongoing.”
SWG3 said: “We are devastated and our deepest sympathy goes out to the families.”
“We will continue to assist the police in their investigation.”
