A nine-year-old girl has become the third child to die after a knife attack at a Taylor Swift-themed dance class in the UK. 

Two other girls, aged six and seven, died in the attack in northwest England on Monday. 

A 17-year-old boy remains in custody accused of murder and attempted murder following the incident in Southport. 

Eight other children suffered stab wounds and five are in critical condition, alongside two adults who were critically injured. 

UK Correspondent Gavin Grey told Ryan Bridge that there is a vigil going on at the sites, with hundreds if not thousands of people attending. 

Taylor Swift herself has also commented on the situation, saying she is in total shock over the loss of life and innocence. 

Grey said that her fans have raised more than $400 thousand for the families of the victims.
