The family of a young university graduate who died after a street assault have paid tribute to him. David Allan, 23, died in hospital on Friday, a day after he was attacked at about 6pm in Wythenshawe, south Manchester. Police have launched a murder inquiry and made some arrests. In a statement, the family said: “David was a much-loved son, whose passing has caused much sorrow amongst his friends and family. “He recently graduated from Plymouth University and had until very recently been working at WHSmith in the Royal Infirmary despite the Coronavirus outbreak, cheerfully serving key workers, patients and visitors alike. “David was saving his wages to take driving lessons to pursue his career goal of becoming a quantity surveyor. “David was a keen and active sportsman and for two years, was a regular member of the university hockey team. At school he loved to fence and shared this passion with children, coaching them at Birmingham University every Saturday. “He will be very much missed.” Murder squad detectives at Greater Manchester police (GMP) have said Allan was attacked by two men. They are appealing for information. DCI Alan Clitherow of GMP, said: “This was a vicious assault which has ultimately resulted in the death of a man and the launch of a murder investigation. “Our thoughts are with the man’s loved ones – to whom I send my condolences at this unimaginable time.” Two men, aged 30 and 33, have been arrested and are in custody for questioning. A man aged 39 and a 42-year-old woman, who were arrested on Thursday, have since been released under investigation.
