Emma Raducanu: Stalker blocked from applying for Wimbledon tickets

While Wimbledon bosses have confidence in their security provisions, which are reviewed annually, the issue has come into sharper focus this year.

It is estimated that around 1,000 people work in the field of security to some extent across the Championships.

In addition to the screening around the ballot, there are also more checks and balances when it comes to those in the queue.

Anyone gaining entry to the Championships that way will have to be registered with Wimbledon – meaning they’ve had to provide personal information.

In the grounds, as well as police and military personnel, there are other discreet members of the security team.

A team of fixated threat specialists are hired in and can assist the player escort team.

There are also behavioural experts who are trained to spot people acting strangely.

There is significant CCTV coverage on site, and if there are concerns around a particular player then a specific CCTV sweep will be done of the seats near to the player and their box.

On court, protection officers are positioned near the players, with more on Centre Court and No.1 Court.

If something spontaneous happens on site, there are response teams walking round the grounds who can come and support staff.

Security teams are also in regular contact with the referees’ office to discuss issues like scheduling.
