Jesse Nwokejiobi: Teenager died from single stab wound to chest in Cambridge

Police believe Jesse Nwokejiobi died in a "targeted attack"

A teenage boy died from a single stab wound to his chest, a post-mortem examination has confirmed.

Police said it believed Jesse Nwokejiobia, 17, of Edinburgh Road, Cambridge, was stabbed in a "targeted attack" in the city on Saturday.

Detectives appealed for social media images. The force said it knew images were being circulated - as one had made its way to them.

Three teenagers have been arrested and released.

Cambridgeshire Police started a murder inquiry after officers were called to an area near Logan's Meadow, a nature reserve on the River Cam, at about 14:50 GMT on Saturday, and the teenager died at the scene, police said.

Supt Adam Gallop said: "Please come forward like others have and help us find answers for Jesse's family."

The force said officers also wanted dashcam footage from anyone who may have been in the St Andrew's Road area between 14:00 and 15:00 on Saturday.

"I want to thank those people who have already come forward, and appeal once again to those that knew Jesse, and maybe know something about this terrible crime," said Sgt Gallop.

Three boys, two aged 14 and one aged 17, were arrested on suspicion of murder and have been released under investigation.

Supt Gallop said he was aware that news of their release "may have caused some concern".

"There are strict policies in place which only allow us to keep people in police custody for a certain length of time without charging," he said.

"I would like to offer reassurance that we have in excess of 100 people working on this investigation, from a dedicated team within the major crime unit, plus specially-trained search officers and an additional 20 investigators from local policing who are assisting with carrying out house-to-house and CCTV inquiries.

"We are working extremely hard to gather evidence and ultimately get justice for a young man who has tragically lost his life."

Supt Gallop added that he wanted to reassure the community that "because they may have something on their phone, it doesn't mean they are in trouble, but evidentially it could help our investigation".
