Tourists and sunbathers enjoyed the hot weather at the River Cam in Cambridge on Tuesday - just yards from two dead bodies lying on the river bank.
Families and holidaymakers continued to soak up the rays at Jesus Green, enjoying picnics and punting on the river, perhaps unaware that two people had died nearby in what was thought to be drugs-related fatalities.
A man and woman, in her 40s, were declared dead at the scene, and police sealed off the area. Another man was taken to Addenbrooke's Hospital for treatment.
Detective Inspector Billy Bremner told the Daily Mail and Cambridge News: "We are aware that two people have died and a third was taken ill at about the same time. We are in the early stages of investigating these tragic deaths and are keeping an open mind as to the cause.
"At this stage we can say that the three people involved are believed to have taken drugs in Cambridge shortly before becoming ill. We would urge anyone who has any information about the supply of drugs in the city to call police."
It is believed there could be a contaminated batch of drugs circulating in the area.
And Kaan Gaygisiz, 17, from Cambridge, said: "It is a packed summer's day and the last thing I thought I'd see was two dead bodies just laying in the grass next to the river. It's unbelievable."
