The men, aged 38 and 45, were arrested yesterday (Wednesday) on suspicion of supplying a class A drug. The 38-year-old has been bailed until August 19 while the other man remains in custody at Parkside Police Station. Officers have also seized a quantity of suspected controlled drugs. A man and woman died in Cambridge on Tuesday (July 16) after it is thought they had taken drugs. The deaths are being treated as unexplained. Chief Inspector Chris Balmer said: We are continuing to work with the coroner to investigate the two deaths on Tuesday and are keeping an open mind as to whether drugs were a factor. We will not tolerate the use and supply of illegal substances and will continue to identify and arrest anyone thought to be involved in such criminality. We have not had any further incidents of people falling ill reported to us since Tuesday but would reiterate that we would urge people not to take any illegal drug or so called legal high because of the dangers they may pose.
