A fan at Millwall v Sheffield United was arrested for stealing a match ball

They're cracking down at The Den.

The reputation of some Millwall fans precedes them but, for Lewisham Metropolitan Police, it's not about that - it's about the law. It's black and white and, if you step outside of the realms of legality, you will be caught. So, whilst some might expect some more extremes at a Millwall match, the big controversy on Saturday - when they beat Sheffield United 2-1 - was that someone stole a football. Someone stole a football. But that didn't stop the police acting swiftly to take action against the perpetrator, arresting him for theft. https://twitter.com/MPSLewisham/status/767030302237679621 The arrested party was not alone, but there's no discrimination when it comes to breaking the law. https://twitter.com/MPSLewisham/status/767031021770567680 https://twitter.com/MPSLewisham/status/767031320576876544 This being 2016 though - and Twitter - people turned their anger at the justice-keepers.

The way the authorities dealt with it seemed extreme to some.

So the police cracked down there as well.
