A teenager with a fear of spiders had her worst nightmare come true after she was bitten by Britain's deadliest arachnid seven times.

Charley Porter 17, was getting ready for bed when she felt an agonising pain on her shoulder after the false widow repeatedly sank its fangs into her flesh.

Her mum had to cut her free from her nightgown and she was taken to hospital after paramedics discovered she had an irregular heartbeat - brought on by the spider's bites.

The family are now having their house, in Ferring, West Sussex, fumigated after an expert told them that there could be a nest in her room.

Archaeology student Charley said: "It was literally my worst nightmare because I hate spiders.

"It took my parents at least 20 minutes to calm me down, there was a lot of screaming. My arm is still hot and hurting now.

"My arm can sometimes go numb like when you have been injected with a needle. It was agony - it went completely red and my lips swelled up."

Charley was taken to Worthing Hospital, in West Sussex, by an ambulance after being bitten last Thursday.

A heart monitor found she had an irregular heartbeat so she was placed on antibiotics and antihistamines.

The family contacted a spider expert who told them that the warmth of the boiler in Charley's room as well as her black painted walls may have attracted the spider in from the cold.

Her mum Patricia Porter said: "The bites were really horrendous and blistery. It was like something out of a horror film."
