Adrian Lubecki ( pictured ) admitted supplying class A controlled drugs and possession with intent to supply a class B drug at Ipswich Crown Court . A teenager who supplied a dangerous batch of 'Superman ' ecstasy pills linked to at least two deaths in the same town has been jailed for five years and four months . Factory worker Adrian Lubecki , 19 , from Ipswich , admitted supplying class A controlled drugs and possession with intent to supply a class B drug . Justas Ropas , 23 , was found dead at his home in Ipswich on Christmas Eve , and Gediminas Kulokas , 24 , was found on New Year 's Day at his home in the Suffolk town . Ipswich Crown Court heard Polish factory worker Lubecki sold the red Superman-branded pills over the Christmas period last year on the streets of Ipswich , Suffolk . He had supplied the drug to Lithuanian machine operator Mr Ropas , who died at home on Christmas Eve . The same Superman pills were linked to the death of Lithuanian labour Mr Kulokas who died on his 24th birthday on New Year 's Day . But the court heard that the supplier of the drug to Mr Kulokas had not been identified and there was no evidence that it was Lubecki . Prosecutor Michael Crimp said : 'The prosecution ca n't say they came from the defendant . ' The drug was also originally linked to the death of British labourer John Hocking , 20 , who died on New Year 's Day at a friend 's home in Rendlesham , Suffolk . But Suffolk Police confirmed today that they no longer believed Mr Hocking had taken the rogue Ecstasy . The deaths prompted Suffolk Police to issue a warning over the Superman-branded pills , which contained the drug PMMA which is said to be five times as toxic as the usual Ecstasy ingredient MDMA . A court heard Lubecki sold the red Superman-branded pills ( pictured ) on the streets of Ipswich , Suffolk . But PMMA which has the full name Paramethoxymethamphetamine is slower acting than MDMA so some users are tempted to take higher doses . The court heard that a housemate of Mr Ropas had contacted Lubecki on December 23 and asked if he could supply some ecstasy tablets . He and Mr Ropas , who was diabetic , then went to meet up with Lubecki in Norwich Road , Ipswich . Mr Crimp said : 'Between them they purchased five ecstasy tablets for £5 each . They were triangular in shape , red and had a 'Superman ' logo on them . ' The men went back to their rented Victorian terraced house and Mr Ropas rook one and a half of the tablets . Mr Crimp said others in the house who had taken ecstasy before said the Superman tablets 'seemed different ' , describing their effect as being slow to start off with and then 'suddenly very strong ' . Lithuanian factory worker Justas Ropas ( pictured ) was found dead on Christmas Eve at his house . He added : 'Tragically the effect on Justas Ropas was that by Christmas Eve he was discovered dead in the flat and the cause of his death was found to be PMMA toxicity . ' The court heard how Lubecki was arrested and then confessed to police where he had hidden his remaining batch of the drug . Officers recovered a bag 461 of the PMMA tablets with the 'Superman ' logo and 49 MDMA tablets with a snail logo . Mr Crimp added : 'They were carefully hidden and not thrown away . ' The court heard how text messages suggested Lubecki had been supplying drugs to people in Ipswich from around last April . Judge John Devaux told him : ' I accept you did n't foresee that your drug dealing might lead to a death . ' Roger Thomson , defending , said Lubecki was devastated by what had happened to Mr Ropas and it was something he would have to live with for the rest of his life . He said Lubecki had got involved in drug dealing to fund his own drug use , but after what happened to Mr Ropas he did n't want anything more to do with drugs . Mr Thomson said that Lubecki had told police where the remaining 'Superman ' tablets were hidden to prevent a further tragedy . Police have warned drug users not to take the suspected rogue batch and to hand in supplies . Chief Superintendent Jon Brighton said : 'Lubecki 's sentencing reflects the seriousness with which drug offences are taken . 'Our message is clear - the supply of dangerous drugs will not be tolerated and every effort will be taken to bring those responsible to justice . 'The tragic deaths of two men in Ipswich led to an extensive police operation , not only to locate anyone supplying the drugs but also to ensure that communities were aware of the dangers and risks associated with taking them . 'We will continue to work with our partners to combat drug dealing in Ipswich and to help those individuals who wish to stop their substance misuse . 'Cases like this show the stark dangers of taking drugs and the simple fact that any illegal drug can result in death . 'We would encourage anyone who takes drugs to seek help from one of the many support agencies available in Ipswich or Suffolk-wide . ' Inquests are due to be held at a later date . Lubecki was sentenced to five years and four months in prison at Ipswich Crown Court .
