A 21-year-old former student from Saudi Arabia was arrested on suspicion of murder after a security guard was shot with a crossbow at the University of Surrey's Manor Park Student Village in Guildford. The incident took place around 10 am, and the security guard, who is in his fifties, is currently in serious condition in the hospital. Eyewitnesses described a chaotic scene, with police and emergency services responding rapidly, including the deployment of a police helicopter. A bystander provided first aid to the injured guard while others restrained the suspect until police arrived. Chief Superintendent Jon Groenen assured the community that there is no ongoing threat and that the police are not seeking any additional suspects. The university has stated that they are fully supporting the police investigation. Authorities are appealing for witnesses to come forward with any information related to the incident.
