Details of a Wimbledon secret tunnel have emerged, with its construction coming after security concerns were raised.
With the world's best tennis players playing and practicing at the All England Club, security and privacy are both paramount. The two-week tournament attracts tens of thousands of spectators every day, on top of a significant media presence.
This year, reigning champion Novak Djokovic has addressed privacy issues amid reports the father of rival Carlos Alcaraz had filmed one of his practice sessions. The top two seeds were both on the practice courts on Monday, and the Serb said he was "not completely relaxed in training" despite public access to the sessions being limited.
