Two arrested in connection with murder of pizza delivery driver Thavisha Lakindu Peiris Two people have been arrested by police over the murder of a pizza delivery driver who was stabbed to death as he was dropping off his last ever order. Thavisha Lakindu Peiris, 25, was found dead in his car on Sunday night in Southey, Sheffield. A 25-year-old man and a 17-year-old are both in custody after being arrested separately on suspicion of murder. Peiris died in what police are calling an apparently random attack that stopped him from completing his last shift and moving on to start his career as an IT consultant. After Peiris did not deliver his last order on 27 November, a co-worker went to search for him. He found Peiris slumped in a silver Toyota Yaris in Southey Crescent at around 10.30pm. His colleagues and police said that he had felt unwell and planned to go home early, but agreed to deliver one last order. Speaking from their home in Sri Lanka, his family described him as the "most caring and loving son a parent could have." Peiris" father and mother, Sarath Mahinda Peiris and Sudarma Narangoda, said: "We sent our son to the UK to study so he can have a better life. We urge anyone who knows anything about our son's tragic death to come forward to help bring whoever is responsible to justice. Please help the police stop another father or mother feel the tragic loss that we are feeling," they added. There are more than 50 police staff involved in the investigation. Detective Superintendent Lisa Ray, the officer leading the murder inquiry, said she did not know why Mr Peiris was killed in an apparently random attack. It is understood his family are making plans to travel to South Yorkshire.
