A man in his 50s is in a serious condition in hospital after being shot with a crossbow on a University of Surrey student accommodation site.
A 21-year-old Saudi national has been arrested on suspicion of attempted murder and taken into custody while police carry out an investigation.
Officers were called to reports of a shooting at Manor Park Student Village, Guildford, at around 10am this morning.
The suspect, who was a former student at the university, was detained at the scene soon after and police say they are working closely with university authorities.
A University of Surrey spokesperson said that the incident took place at around 9.50am and that a member of the campus safety team was "seriously injured".
Police have appealed for information and witnesses to come forward.
The victim remains in hospital in a serious condition, police said.
Chief Superintendent Jon Groenen said: "I appreciate that this incident will cause concern amongst our local communities, and I can reassure that we are not looking for anyone else in relation to this incident.
"We are working closely with the university as our investigation progresses.
"The suspect was detained at the scene shortly after the incident and an investigation is now underway to establish the circumstances of the assault."
He continued: "The victim remains in a serious condition in hospital and his next of kin are aware and are being supported by officers."
