An EU Referendum polling station was forced to shut just hours before voting closed after a man collapsed outside it after being stabbed.
The man collapsed in Waverley Road, Huddersfield, at about 5.15pm. Police had to close the polling station for about 30 minutes to preserve the crime scene.
West Yorkshire Police said they believed the man was stabbed in nearby Greenhead Park and then walked to where he collapsed. They said the attack was not linked to the referendum.
One voter took a photo of the crime scene, saying: "Looks like I won't be voting today."
The man's injuries were "serious but not life-threatening".
Three people went to his aid when he collapsed to apply pressure to the wound, The Huddersfield Examiner reported.
A 19-year-old man has been arrested in connection with the incident.
The police are appealing for anyone who has information about the incident to contact police on 101 quoting log 1338 of Thursday 23 June.
