Big Brother forced to make major change to house after multiple security breaches

It seems fans of Big Brother have been trying to meddle with this year's series by communicating messages to the housemates from the outside world.

It's understood that TV show execs have now been forced to make major changes including to security for the remainder of the show.

Pranksters have, on two occasions, been able to bat tennis balls into the garden in a bid to communicate with the housemates who are going into their third week.

ITV has categorically ruled out that production has anything to do with the stunt, and that they have come from viewers of the iconic show.

Housemates read the messages aloud on the balls before bosses ordered them indoors and put the house on lockdown while it was investigated.

The first round of balls claimed that housemate Lynx had a girlfriend on the outside and falsely claimed there was another secret mole in the house, sending the cast into chaos.

The menace then struck again during Tuesday's show this week, firing in notes about Rochelle and Philip being the favourite to win.

Another ball said that 'Rochelle was right' regarding her row with Pauline and Johanne.

LADbible understands that measures are now being taken to prevent outside fans from meddling with the show again.

A source has said that netting is going to be installed over the garden, meaning balls and any other items thrown in would not be able to land on the set.

It is not known how the balls were able to reach the garden or how close the fan was able to get to the West London-based set.

It has also since been reported that security will be increased around the site to keep a beady eye on any other potential antics.

Tensions have simmered over again this week as the house was transformed into the 'House of Nothing'.

Producers stripped the housemates of their voices, their belongings and even the furniture, with them completing tasks and challenges to win them back throughout the week.

This year’s show has already faced some serious drama including a row over comments Rochelle made to quadruple amputee Charlotte and Jedward being ‘booted out’ of the house.

More drama made headlines on Thursday, as Big Brother housemates attempted to get to the bottom of a housemate who had an accident on the toilet floor.

Nominations have also been cast this week, with Rochelle and Johanne both up for eviction on Friday night's show (2 October).
