The family of a cyclist killed in a collision on a North Tyneside road has appealed for the driver responsible to come forward.
Paul Brady had recently graduated from Cambridge University
Paul Brady, 23, of Lumley Road in Durham, died of multiple injuries after being knocked off his bike on the A19, near Silverlink on 18 January.
Police believe a heavy goods vehicle may have been involved and the driver may not be aware of the death.
Mr Brady's family paid tribute to "a wonderful young man".
His father John, said: "He had his whole life ahead of him. He had just finished a degree at Cambridge University and was working for a year prior to taking a Masters degree at Durham.
"His family and friends desperately need to know what happened."
Paul's elder brother Christopher added: "This accident has robbed our family of the fiercely intelligent, kind, principled, wonderful human being that our Paul was.
"If you know something or if you saw something, however insignificant you at first suppose it to be, please, please tell the police now and give us some peace of mind."
The accident happened on the northbound carriageway of the A19, north of the Silverlink roundabout, just before 0750 GMT, on Friday, 18 January.
