Police warning over flares and smoke bombs at Old Firm game
Police plan to use specially trained dogs to identify anyone attempting to take flares or smoke bombs into Sunday's Old Firm game at Celtic Park.
The match is the final derby of the season between champions Celtic and Rangers, who are in administration.
Strathclyde Police said there had been an increase in the number of flares and smoke bombs at football matches.
The force said anyone caught with the items inside or outside the ground would be arrested.
Ch Sup Wayne Mawson said: "Over recent weeks, we have seen an increase in the number of flares and smoke bombs set off at football matches.
"This can be very frightening for people attending the match - they represent a significant risk to the safety of people and can mar the occasion for fans there to support their team.
"We will have specially trained dogs out this weekend and anyone found in possession of a flare or a smoke bomb will be arrested."
Ch Sup Mawson also warned that "anybody arrested for offences of a serious nature, will be subject of an application for a football banning order".
He added: "As with any major event, public safety is paramount and there will be high visibility policing and additional patrols in and around the surrounding area."
