Update 7pm, Sunday, May 8

Police have confirmed that they have made another arrest in connection with a murder investigation in Langley. 

A teenage boy from Slough remains in police custody after being arrested yesterday (Saturday), Thames Valley Police said. 

The force is continuing to appeal for information after an 18-year-old man was fatally stabbed in Trelawney Avenue on Thursday evening (May 5). 

Two teenage boys from Slough, who have previously been arrested in connection with the investigation, remain in police custody.

Thames Valley Police added that a 17-year-old boy from Slough, who cannot be named for legal reasons, was charged yesterday (Saturday) with affray and possession of a knife/bladed article in a public place.

He is due to appear at Reading Magistrates’ Court tomorrow (Monday). 

The force added that a post-mortem examination carried out yesterday also concluded the victim’s cause of death as a stab wound to the chest.

Detective Chief Inspector Will Crowther, of the Thames Valley Police Major Crime Unit, said: “Our thoughts remain with the victim’s family at this most difficult time and I would ask that their privacy is respected.

“I would like to repeat the request for anyone who may have seen the incident outside the Trelawney Avenue shops in Langley at about 7.15pm on Thursday or who has any information about this incident to please come forward.

“You can do so by calling 101 or making a report on our website, quoting reference 2010 of 5 May.

“Alternatively, for 100 per cent anonymity, contact the independent charity, Crimestoppers, by calling 0800 555 111 or via its website.

“Officers have been conducting extra patrols in the area following the incident and I would encourage anyone who is worried to tell them about their concerns.”

Police have arrested three teenage boys in connection with a murder investigation in Langley. 

Thames Valley Police's Major Crime Unit launched a murder probe on Friday following the fatal stabbing of an 18-year-old man in Trelawney Avenue on Thursday evening.

The three boys, all from Slough, remain in police custody, while the force continues to appeal for witnesses to come forward following the incident earlier this week. 

Police urged the public not to watch or share videos relating to the incident which have been circulating, calling these 'abhorrent'. 

Senior investigating officer, Detective Superintendent Kevin Brown, head of the Major Crime Unit, said: “We have made three arrests in connection to our thorough investigation into the tragic stabbing in Trelawney Avenue on Thursday evening.

“Our thoughts remain with the victim’s family at this most difficult time and I would ask that their privacy is respected.

“We are aware of videos circulating on social media relating to the incident and I would urge the public not to share them.

“This practice is abhorrent and has caused significant distress to the victim’s family and friends.

“Not only do they include distressing images, the sharing and viewing of them could lead to investigative difficulties and indeed open the perpetrators up to investigation for offences following the arrests.

“So please do not share or view these images or videos as they are not helpful to the family or police at this critical stage of the investigation.

“I would also like to repeat my request for anyone who may have seen the incident outside the Trelawney Avenue shops in Langley at about 7.15pm on Thursday or who has any information about this incident to please come forward.

“You can do so by calling 101 or making a report on our website, quoting reference 2010 of 5 May.

“Alternatively, for 100 per cent anonymity, contact the independent charity, Crimestoppers, by calling 0800 555 111 or via its website.”

Local policing area commander for Slough, Superintendent Lee Barnham, added: “Thames Valley Police will not tolerate carrying or using weapons in Slough.

“The community will be shocked by what has happened but you will see an increased police presence.

“If you have any concerns or questions I would encourage you to speak with my officers.”
