According to documents seen by Telegraph Sport, the LTA confirmed the on-site player doctor could not see members of a player’s support team or coaches.

The tournament clarified that the “spectator medical provision” available on site consisted only of emergency paramedics, not registered doctors with any specialism.

The player’s father was directed to attend a local hospital for medical assessment and treatment. He went to hospital on Tuesday, where he was in a waiting room for approximately three hours before returning to a hotel to sleep.

“This happened about one hour before I had to play my match, which I still had to go out and play,” McCabe said.

McCabe has asked for the adults who witnessed the incident to be identified and CCTV/camera footage preserved.

Regarding the outcome of the police involvement, an email from Claire Daniel-Lepore, the chief executive of Edgbaston Priory Club, where the Birmingham Open is hosted, claims that the police “have confirmed they are taking no further action”.

However, further emails note the McCabes reserve their rights to pursue a Victims’ Right to Review regarding any “no further action” (NFA) decision. They argue the police should review the newly gathered hospital records, CCTV and independent adult witness statements before making a final determination.

A joint statement from the Edgbaston Priory Club, LTA and ATP said: “There is an ongoing investigation being led by Edgbaston Priory Club with support from the ATP and LTA in relation to an incident during the Lexus Birmingham Open on Monday 1st June.

“This incident involves an allegation made against a member of Edgbaston Priory Club staff by a player’s coach and is currently being reviewed by an investigating officer.

“We will be making no further comment whilst the investigation is ongoing.”
