Christian Horner has refuted the allegations to Dutch publication De Telegraaf, though the exact nature of the complaint remains unclear.
The BBC has stated that they pertain to ‘inappropriate and controlling behaviour’, yet Red Bull has not verified this.
Interest in the investigation has extended beyond the confines of the Red Bull headquarters in Milton Keynes.
It is purported that former Formula One Group chief Ecclestone has been engaging in telephone conversations with Horner.

As per Motorsport-Total, the 93-year-old, a trusted confidant of the Red Bull team principal, has intervened in an advisory capacity and has conversed with Horner on numerous occasions. F1 CEO Stefano Domenicali has also reportedly been in touch with Horner.
Horner was observed arriving at his hearing in the rear of a black car. Initially anticipated to occur at the team’s F1 HQ, the hearing was relocated to London to evade extensive media presence.
Red Bull has declared they will refrain from commenting until the investigation has been fully concluded. Thus, it remains uncertain whether Horner will lead them into the 2024 F1 season.
The team is scheduled to unveil their RB20 car on Thursday, but uncertainties persist regarding whether Horner will oversee the presentation. The new vehicle is purported to be a development of their highly successful RB19, in which Max Verstappen clinched a record-breaking World Championship.
Red Bull emphasise that they are treating the allegations “extremely seriously” and are eager for a prompt resolution. However, it remains unclear whether the investigation will extend into the forthcoming season.
The 2024 campaign commences with the Bahrain Grand Prix on March 2, with practice and qualifying sessions occurring in the days preceding.

This grants Red Bull three weeks to conclude the probe if they wish to avoid it continuing into the season.
Horner has been instrumental to Red Bull’s achievements since assuming leadership of the team in their inaugural F1 season in 2005.
Verstappen has secured the last three Drivers’ Championships, with Red Bull also leading in the last two Constructors’ Championships.
