A chief executive caught in a suspected affair with a colleague at a Coldplay concert has been put under investigation by his company.

Astronomer, a New York-based data company, said its directors had begun a “formal investigation” after Andy Byron, the company’s chief executive officer, was filmed with his arms draped over Kristin Cabot, its HR director, on a “kiss cam”.

When the pair appeared on camera, Ms Cabot covered her face and the pair ducked out of sight, prompting Chris Martin, the band’s singer, to suggest they were either “having an affair” or were “very shy”.
