Around 8.20pm, on Saturday, February, 27, 2021, police received a report of a disturbance at Greenfield Park football pitches in Duror Street, Glasgow.
A group of young people were in the car park area when a group of older men attacked them, resulting in three young men being stabbed.
Emergency services attended and three men, two aged 21 and one aged 19, were taken to the Glasgow Royal Infirmary where they were treated for stab wounds.
Officers are treating the incidents as two attempted murders and a serious assault.
Since the attacks, officers have been carrying out extensive enquiries and are checking CCTV images for any relevant information which could assist the investigation.
Detective Sergeant Stephen Greenshields, said: “This has been an unprovoked attack on a group of young people which could have left them dead.
"The injuries inflicted were severe and extremely serious. It is unacceptable that people think they can behave in such a way and think they will get away with it.
"Let me assure you, they will not. A team of officers is working to establish the identities of the men responsible for this crime.
“I would appeal to members of the public who were in the area at the time who may have witnessed something to contact us. Any small piece of information could assist us as we piece everything together and find those responsible.”
Additional patrols will be in the area to provide reassurance to the local community and anyone with concerns can approach these officers.
