A CORONER has told the devastated parents of a tot who choked to death on an inch-long screw that no-one was to blame for the tragedy.

Muhammad Ibraheem Mirza, who had six siblings, had been in an upstairs bedroom with some of them at their home in Hudson Street, Laisterdyke, when he found and swallowed the object in the early evening of July 22 this year.

The 13-month-old was being supervised by the older children while his father showered after returning from prayers at a mosque and his mother was in the downstairs kitchen.

Muhammed''s father Naseem Mirza said he rushed upstairs after hearing his 11-year-old daughter shouting his son's name.

He saw her sitting on the toilet in the bathroom with Muhammad on her lap and she was trying to poke something out of his mouth with her finger.

Mr Mirza took him from her and carried him downstairs while his frantic wife dialled 999 - an operator was giving resuscitation instructions when paramedics arrived.

Despite continued attempts to save him in the ambulance and once at Bradford Royal Infirmary he was pronounced dead at the Accident & Emergency Department.

A one-inch long screw had blocked his airway causing him to suffocate and his heart to stop.

Police gathered evidence at the house but the inquest in Bradford was today told Muhammad's parents had later told health visitors, including a sudden child death specialist, they did not know where the screw had come from.

The health workers were satisfied to record the incident as "a tragic accident in a very busy household with seven young children" - there had been nothing to suggest any neglect.

Muhammad had been a very active little boy, kept clean and well-cared for, he had been able to walk since he was 12-months-old and was using a few words, the inquest was told.

Recording a verdict of accidental death, Assistant Bradford Coroner Oliver Longstaff said: "This little boy had been brought up in a caring and loving environment by his parents with his siblings.

"He inadvertently put a screw in his mouth and swallowed it. It got trapped and he choked and despite the best efforts of his parents, paramedics and doctors he died.

"The death of an infant is a disaster and impossible to bear. It was quite clearly an event for which there was no direct responsibility. It was an accident."
