Video: Arsenal and Spurs fans in violent clashes outside White Hart Lane
Today's North London Derby was hard-fought on the pitch, but it seems some fans took the attritional atmosphere too far.
Things seemed to boil over between the two sets of fans before kick-off, with one supporter pictured with a bloodied head as a brawl broke out.
Various outlets report that police were required to intervene in proceedings, with tensions boiling over ahead of the 2-2 Premier League draw.
It is not the first time this season that things have got out of hand outside Tottenham's ground, with one man being hospitalised following a reported stabbing before Spurs' league meeting with West Ham in November.
