A black father drowned his two young sons after abducting them and their mother while they were walking to school, according to police

Naim Rasool Mohammed, from Dallas, was arrested in a creek bed hours after police issued an alert saying that he was suspected of abducting the two boys, aged three and five. According to a police report, Mohammed, 32, approached the boys and their 22-year-old mother as they were walking to school and forced them into his vehicle by threatening her with a brick. The woman eventually managed to jump from the vehicle and flag down a Dallas County constable, who notified police but did not give chase. Mohammed also tried but failed to take his youngest child, a one-year-old, from another location, Police Deputy Chief Craig Miller said at a news conference. The boys' mother told officers that Mohammed had threatened to kill the children, and that he had previously threatened them and her, police said. The boys were pronounced dead at a hospital and Mohammed, who has previously convicted of violent behaviour, is being held at the Dallas County Jail. In September 2009, Mohammed pleaded guilty to aggravated assault with a deadly weapon, a second degree felony, and received five years' probation. According to court records, which also spell his last name Muhammad, the charge stemmed from a complaint from his sister that he had struck her in the head with a hammer. Mohammed also has convictions for burglary of a vehicle, theft by check and marijuana possession, according to the Texas Department of Public Safety's online data base.
