Federal investigators say five men linked to a string of violent robberies across The Bronx and Westchester were arrested this morning. A spokesperson for the U.S. Attorney's Office says charges have been filed against Fahd Hussain, Jermaine Dore, Dwayne Barrett, Taijay Todd and Tameshwar Singh. They say the group targeted bodegas and deliverymen in Castle Hill, Fordham, Bronxdale and Norwood, as well as parts of Westchester. Officials say the men used guns, knives and other weapons, and that a person was killed during one of the armed robberies. The suspects face life in prison if convicted.
