Hundreds of people came together to hold a vigil for MP Jo Cox, who was killed yesterday in Birstall, West Yorkshire.
Jo worked as a Member of Parliament for the Labour party representing the Batley and Spen area of Yorkshire.
On Thursday, Jo was attacked near to where she had been holding a constituency surgery, where local people can talk to her about any problems they have.
A local man has been arrested.
