Britain's Ellie Simmonds has paralympic swimming records taken by USA's Victoria Arlen
Teenager Victoria Arlen has captured yet another of Britain's Ellie Simmonds' world records at the United States Paralympic swimming trials.
The 16 year old from New Hampshire beat the Simmonds’ S6 category 400m world best on the first day of the trials in North Dakota.
She then went one better by smashing Simmonds' 2012 World Championships 100m freestyle time of one minute 15.97 seconds by posting an extremely impressive 1:14.74.
Her 400m time of 5:24.46 on Friday 15 June beat Simmonds' previous record of 5:25.20, which the two-time Paralympic champion set at last summer's European Championships in Berlin.
Simmonds is the current world and Paralympic champion over 100 and 400m but was beaten to the gold medal by Holland’s Mirjam De Koning-Peper in the 100m final in Berlin.
Arlen, is a former New England-ranked champion swimmer was paralysed by a virus in 2006, which affected her spinal cord and also left her in a vegetative state for two years.
She only made her return to the pool last year but after months of hard work has now secured a place on the 34-person US team for London 2012.
US swimmers set an incredible 12 world records at the trials, with seven-time Paralympic gold medallist Jessica Long claiming half of them.
The 20 year old, who was adopted from a Russian orphanage at 13 months old and had her legs amputated aged 18 months, set new marks in the 200m individual medley (twice), 100m butterfly, 400m freestyle and the 50 and 100m breaststroke.
