Police have named the teen who was found in the grounds of Belfast City Hospital as Tara Wright.
Police investigating the circumstances surrounding the death of the 17-year-old and the road traffic collision which occurred on the Ballygowan Road at its junction with Manse Road during the early hours of Sunday 24th March continue to appeal for information.
Inspector Nigel Henry said: “Firstly, I would like to extend my sympathies to the family of Tara at this very sad time.
"Our investigation is at an early stage, however, we do believe that Tara was injured during the one vehicle road traffic collision on the Ballygowan Road.
“We are appealing to anyone who witnessed either the silver Mercedes or grey MG to contact us to assist us with our enquiries. We also believe that a grey coloured MG vehicle conveyed Tara to the area of Belfast City Hospital therefore we are also appealing to anyone who witnessed this vehicle between the Ballygowan Road and the Hospital to contact police.
“Investigating officers arrested four males aged 20, 21, 28 and 30 yesterday. They have since been released on bail and are assisting us with establishing the circumstances leading to Tara’s death.
"If you have information about the collision, which you believe could assist our investigation, please pick up the phone and call us on the non-emergency number 101, quoting reference number 227 of 24/03/19.
