The Wear-Tees derby was the most heavily policed football match in the Championship last season, it has been revealed.
Northumbria Police put on a show of strength when Middlesbrough travelled to the Stadium of Light to take on Sunderland AFC in February.
In total there were 587 officers assigned to the clash - a ratio of one police officer for every 50 fans in attendance.
And this level of police protection cost Sunderland AFC £55,413, figures from the BBC Shared Data Unit show.
Despite the huge police presence, the Stadium of Light was still almost half empty, with 40.7% of seats unfilled.
In the Premier League, the most heavily policed Newcastle United home game during the 2017/18 season was the Everton match on December 13.
Figures show there were 62 officers in attendance at that game, which in a packed out St James’s Park where more than 99% of seats were filled meant there was one police officer for every 858 fans.
Chief Superintendent Sarah Pitt, of Northumbria Police, said the figures were “quite misleading”, as different forces allocate policing differently across the country.
She said: “Our over-riding priority is to ensure the safety of the public, and decisions over policing levels at football matches are made based on a number of different factors to achieve that aim.
“With regard to the particular fixture of Sunderland versus Middlesbrough, this is a local derby which has historically resulted in the need for increased numbers of officers.
“However, the policing footprint at this fixture has reduced in recent years as a result of pro-active work undertaken with both sets of supporters.
“We have already praised fans in the North East for their excellent behaviour over the course of last season.
“Supporters in this region are among the most knowledgeable and passionate in the world, and we look forward to building on our healthy relationship during the upcoming 2018/19 campaign.”
