A man’s face was slashed with a knife during an alleged assault in an Islington pub while Arsenal were playing Manchester City last year.
The incident happened in Tollington Park at around 8.30pm on April 26 when the 33-year-old victim was confronted by another and they had a “brief verbal altercation”.
The Metropolitan Police said the other man “produced a knife and slashed the victim's face, leaving a deep laceration from his left cheek to his lip”.
“He was taken to hospital by paramedics," a statement added. “Though not life-threatening, the victim continues to receive treatment for his injury.”
The suspect left before police arrived. Following extensive enquiries they are now turning to the public for help to identify him.
On Saturday, the Met shared a video and photo of a man wearing a green cap, who they want to speak to in connection.
Detective constable Danitza Iniesta, from the local policing team in Islington, said: "The pub was busy with people who were watching the Arsenal v Manchester City game that night.
"We believe the victim and suspect spoke a few times throughout the evening without issue, before this horrific act of violence unfolded.
"If you were there that evening, or you know the man pictured, I urge you to contact us immediately."
The police did not state which pub the incident played out in, however, the only venue of its type in Tollington Park is The Park Tavern - around one mile from the Emirates Stadium.
The video released shows the man in question hugging a friend before returning to the bar. He is wearing green and has glasses on.
