A vice president of the world’s largest live entertainment company filmed up women’s skirts with a pen camera on his London commute.

Andrew Macrae, 43, was spotted by an off-duty Met officer using the device concealed in a laptop bag, which he placed on the platform and train floor between unsuspecting victims’ legs.

When officers searched his home in Redhill they discovered Macrae, VP of finance and strategic initiatives at Live Nation Entertainment, had also been secretly filming a female neighbour and house guest, and had hoarded approximately 49,000 more images.

The married father this week admitted one count of outraging public decency between Clapham Junction and Vauxhall stations on July 19.

He also pleaded guilty to seven counts of voyeurism for the purpose of sexual gratification in filming offences at his home over three years.

Macrae, who has worked at Live Nation since 2004, was caught when the off-duty detective saw him acting suspiciously.

Prosecutor Angela Mehadio told Camberwell Green magistrates: “He had a black laptop bag on the floor, which was zipped up, and a black pen with gold trim poking out of it.

“The defendant seemed to be changing the angle of the bag, which he had placed between the legs of a blonde female wearing a red summer dress.”

Macrae was arrested and taken to a south London police station.

Ms Mehadio told the court: “He admitted his intention was to film up skirts for personal and sexual gratification.”

Macrae, who has moved to his parents’ home in Shropshire, did not enter pleas on two further counts of outraging public decency. He was bailed to appear at Inner London crown court on November 7 for sentencing.

Live Nation, which dismissed Macrae after his arrest, said in a statement: “This matter is still before the courts and as such we are unable to comment on the case.

"We can confirm that these charges have been made against the individual personally and that he was terminated by Live Nation Entertainment in July 2017 following his arrest.

"Live Nation strongly condemns Macrae’s acts and is outraged by his offensive and criminal behavior which has no place at our company, city or the world at large.”
