Northumbria Police said they are not looking for anyone else in connection with the death of a Zimbabwean student on a popular cycle route.
Officers confirmed there was "no third party involvement" after Sijabuliso Nkala was found with a stab wound and later died close to the Oval, in Walker, on the 11th of July.
The 24-year-old Newcastle University student, from Jesmond, was found in bushes next to the popular tourist trail with a single knife wound to the chest.
Det Supt Roger Ford said: "My sympathies are with the family and friends of Mr Nikala at this time.
"I would also like to thank all the people who contacted police following our appeal for information. A report is being prepared for the coroner."
The head of the faculty where Mr Nkala was studying also paid tribute to the "polite and hardworking" man.
Prof Barrie Mecrow, head of the School of Electrical and Electronic Engineering, said:
"This very sad news of the death of Sijabuliso Nkala, third year Electrical Engineering student, has come as a terrible shock to us all. Affectionately known as Jabu, he was a very modest young man who spoke well of everyone. Around the School, he always had a smile on his face and a positive attitude towards academic work. He showed initiative in his approach to coursework and was extremely polite and hardworking. He was a focused individual who will be remembered for his smile and his enthusiasm."
Officers attempted CPR at the scene, where the student’s bike was also found, but nothing could be done to save him.
