Boys, aged 14, among three arrests after 17-year-old stabbed near Cambridge nature reserve

Three teenagers, including two 14-year-old boys, have been arrested after a 17-year-old boy was stabbed to death in a "targeted attack" near a city centre nature reserve.

Police were called to the scene by the ambulance service after the boy was stabbed at around 2.52pm on Saturday afternoon near Logan's Meadow in Cambridge.

The teenager was pronounced dead four minutes later.

Logan's Meadow is a small nature reserve next to the River Cam.

Police subsequently launched a murder investigation and made three arrests late on Saturday night.

They included a 14-year-old boy who was arrested at his home in Cambridge at about 11.30pm, while another 14-year-old boy and a 17-year-old boy were both arrested at their homes in South Cambridgeshire around midnight.

All three were arrested on suspicion of murder and remain in custody at Thorpe Wood Police Station in Peterborough.

“We believe there were members of the public at the scene who spoke with paramedics but left before our officers arrived. I am directly appealing for these people to make contact with us please," Detective Superintendent Carl Foster, from the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit, said.“I would appeal to anyone with information to get in touch with us as a matter of urgency.“

There's a lot of police tape in the area, and Equiano Bridge is completely shut.

I can see that there are two tents up and several forensic officers in their white suits, looking for evidence.

The Logan's Meadow nature reserve is completely cordoned off as well, so it's a huge area that's being affected.

It's a nice sunny Sunday in Cambridge, there's lots of runners, lots of people on the river rowing down the River Cam, and loads of cyclists too, so it's a really busy area.

It's obviously drawing quite a lot of attention, a lot of people are coming to have a look because the tents are quite visible from the river.

Most people are shocked at the ages of the people involved.

Mark Wilkinson lives close to where the stabbing happened and told me: "I often walk my dog in that field, so it's really worrying that it happened in broad daylight. Loads of people are around here in the day, lots of people walk in the nature reserve. I actually saw the air ambulance land there yesterday afternoon and came out to see what was going on."

His mother Tina Wilkinson was equally stunned: "I just can't believe it happened in the middle of the day, and they're so young," she said.

"It's worrying really that something like this can happen. It's just awful."
