Police are hunting Rangers fans who left off smoke bombs, bangers and flares at the match against Livingston on Wednesday night after two fellow Light Blues supporters were hurt, including a child
A 13-year old boy required treatment to his eyes while a 26-year-old woman sustained a minor leg injury. Both were treated by medics at the stadium and did not have to attend hospital.
A police officer was also hit by a coin thrown by a fan in the away end during the Betfred League Cup quarter-final tie that Rangers won 1-0.
Chief Inspector Neil Mitchell, the officer in charge of the policing operation for the match said: "Taking pyrotechnics into a football stadium is not only an offence, it is extremely dangerous.
“The injuries sustained by the woman and boy caused by the devices, and the consequences, could have had been so much worse.
"Once again it is extremely disappointing and worrying that despite repeated warnings about the risk pyrotechnics bring, a small minority continue to smuggle them into matches.
"The vast majority of those who attended the match were well-behaved and enjoyed the game. However, following the actions of a small group of their fellow supporters, two people were injured.
“It is only down to luck that their injuries were minor. If this continues it can only be a matter of time before someone is injured more seriously.
"One of my officers was also struck by a coin thrown from the same group of supporters. This is also unacceptable and will not be tolerated.
"We have a retrospective investigation ongoing and are working closely with both clubs to identify those responsible. I can confirm that we are following a positive line of enquiry.
"I urge anyone at the game who witnessed the use of these pyrotechnics and can assist in our enquiries to contact police on 101, quoting incident number 2394 of 25 September 2019.
"We will deal with all those responsible in a robust manner including seeking football banning orders through the courts."
Rangers 'ultras' group the Union Bears issued a statement following the incident.
The group defended the use of flares and smoke bombs despite the risk they pose to others, such as supporters with asthma, although they urged fans not to use firecrackers in crowded areas.
The statement said: “The Union Bears support the safe use of pyrotechnics inside and outside football stadiums.
“Whilst this is our stance, we would like to discourage supporters from using firecrackers inside the stands. These firecrackers are endangering our supporters when set off in crowded areas.”
