Mr Kareem said: “Given the fact that the killers will know who I am because we were publicly trying to seek justice, I have to be vigilant. “I don’t know how they would react when they faced me. “I have to be cautious every time I leave the house. “If a car pulls up, an unknown vehicle, I’m at a loss when things like that happen. It’s something I’ve had to live with and learn to deal with.” Image: The shooting took place in Shepherd’s Bush, west London “I don’t want to live a life of fear” Kareem, 29, said he had considered moving to a different area but didn’t want to be “pushed away”. “I don’t want to live a life of fear and I think I need to get away from what happened,” she added. “The people who need my support are here.
