"Louis heard the noise because he wasn't sleeping well with jet-lag and at first he thought it would be another fan who had sneaked past minders," an insider is quoted as saying.
"When he saw it was a small naked man he called security, who sorted it out. This bloke wasn't even a hotel guest, but a drunk who was looking for a toilet."
The band, who are touring the US with Olly Murs this summer, reportedly plan to hire extra security after they were mobbed by a large crowd of female fans in New York City.
