One Direction star Louis Tomlinson has installed a state of the art panic room at his home to protect him from crazed intruders.

The 21-year-old star has spent £15,000 on the safety measure, after jealous fans sent death threats to his girlfriend Eleanor Calder.

A source close to the band told The Sun: "Louis loves the fans and isn’t overwhelmed with paranoia. He’s just a realist about the dangers of being in the spotlight.

"One Direction followers are notorious for tracking the lads down, so that’s made him a bit cautious."
