In the latest incident bricks were thrown through the windows of the family's Mount Vernon home in the early hours of Monday morning.The nine-year-old boy was not in the room as he and his five-year-old sister, their father and his girlfriend were staying with relatives.The attack comes just days after their car was set on fire. That vehicle replaced another car which was also attacked a week earlier.The family said the people behind the attacks were "animals".Imelia Farbiszewska said: "We have no idea why this is happening. Everyone around us, all our neighbours, are really friendly."There is no words to describe those who are doing this - they are animals."The children's father Marcin Zyczko added: "It's the car one time, then the house, I don't want to think about what could be next."We don't feel safe in this house. I go to work and just worry about what could happen."Imelia added: "We just don't want to live here anymore."We can't bring the children back and we can't sleep in this house."It's really possible something bad could happen to us."The family told UTV they could not be certain if a racist element was behind the attacks.Police said they are still investigating a possible motive and have appealed for information.
