Mingzi Yang death: Police appeal to find cyclist
Police investigating the suspected murder of a Chinese student are appealing for anyone who saw a cyclist wearing a blue safety helmet on the day she died.
Officers say they want to speak to the man who was seen in the area near 29-year-old Mingzi Yang's home in Sincil Bank, Lincoln.
The student, who had a young son, was found dead at her house by police.
A man has been charged with murder and has been remanded in custody.
Miss Yang had moved to the UK from China in 2008 and had been studying English at Lincoln College.
'Friendly young lady'
Det Ch Insp Martin Holvey, from the East Midlands Special Operations Unit, said officers had been gathering information to build up a picture of the student's life.
He said they wanted to speak to a man who was seen cycling in the Sincil Bank area between 07:00 and 13:00 on the day Miss Yang died.
"She [Mingzi] studied at Lincoln College and is widely described as a well-liked, friendly young lady who got on well with her tutors and peers," said Det Ch Insp Holvey.
"Her college friends, her friends in the community, people who knew her from the school gates - we would like to hear from anyone who knew her in any way."
A Home Office post mortem examination has been carried out but further tests are being done to establish the exact cause of her death.
Det Ch Insp said Miss Yang's parents in China had been contacted and were "understandably distraught".
Wai Hong Tsang, aged 33, from Bluebell Road, Grimsby, has been charged with Miss Yang's murder and will next appear at Lincoln Crown Court in September.
