A TEENAGER was left needing life-saving surgery after a "cowardly" cyclist stabbed him in a "ride by".

Detectives from West Yorkshire Police have issued an appeal after the stabbing in Leeds city centre, on Sunday, May 30.

A 19-year-old man was walking home with friends in Wade Lane at about 1.50am.

Suddenly, a male cyclist rode up behind him on a mountain bike and stabbed him in the back.

The suspect then cycled off along Lovell Park Road towards Little London.

The victim suffered a single stab wound and was rushed to hospital.

He had to undergo life-saving surgery before being kept in hospital for a number of days while he recovered.

It is believed the attack was targeted, but the motive behind it is still unknown.

The suspect was described as mixed race and aged 19 to 20.

He is said to be 5ft 9ins tall and of medium build.

He was wearing a dark coloured tracksuit, a face covering and was riding a dark coloured mountain bike.

Detective Inspector James Entwistle, of Leeds District CID, said: “This was a cowardly attack from behind on the victim who was simply walking along the pavement chatting with friends at the time.

“We believe the victim has been targeted but the motive for the attack remains unknown.

“We are continuing to carry out enquiries to identify the suspect and would like to hear from anyone with any information that could assist the investigation, particularly anyone who saw him in the area or who has any relevant CCTV or dashcam footage.”
