Jones has increased protection around the team’s base in the capital after QPR fans threatened reprisals, reports the Daily Mail.
Seven years ago, QPR were woken ahead of their League One play-off date with Cardiff when the matches were staged at the Millennium Stadium.
The fire alarm was set off in the middle of the night and, now that Cardiff head to London to face Blackpool, rumours have grown that Rangers’ fans will serve up a revenge attack.
Jones said: “We do have security this year. We have taken as much precaution as we can do.”
