Police have arrested five men in Scotland over a disturbance before the national football team's match against England at Wembley last year.
The Met said officers from its Public Order Investigations Team made two arrests in Glasgow, two in Dundee and another in Bonnybridge, near Falkirk.
All five men were bailed pending further inquiries.
The arrests relate to a fight in Maiden Lane, Covent Garden, involving supporters of both sides.
Officers from Operation Arrowtip, which investigates football related disorder, made the arrests on Wednesday and Thursday.
The men, who have been held on suspicion of violent disorder, are all aged between 19 and 27.
Supt Andy Barnes, who leads Operation Arrowtip, said: "Violence amongst supporters has no place in football, be it before, during or after a match.
"The vast majority of supporters who attended last year's England vs Scotland match behaved in the right spirit and this was an isolated incident.
"These arrests show that anyone who chooses to engage in violence will be pursued by officers and arrested."
Inspector Knacker of The Yard later told The JT:
" This marks only a very preliminary stage in our enquiries, we're also following up leads surrounding a very serious incident involving English and Scottish fans at a place called Bannockburn in that Scotchland on or around June 1314.
We'll be sending out a very clear message that medieval violence between football supporters is never acceptable even if it happened 700 years ago."
It is thought that the resources expended in tracing participants in a pagga outside a London boozer nine months ago means that unfortunately The Met will not be able to identify the one serving officer who didn't actively try to fit up the Lawrence family after their son was murdered 25 years ago.
