A toddler died when she fell out of a window from a block of flats while her parents were sleeping, an inquest has heard.

Muna Abdirazak, aged 21 months, suffered severe head injuries when she plunged from the third floor of the building in Bristol.

Avon Coroner's Court heard Muna climbed out of bed in the early hours of the morning on July 15 2013 and pushed open the kitchen door.

She is believed to have clambered on to a wooden chair and then on to the kitchen table - before toppling out of the open window next to it.

Muna's horrified parents, Layla Mohamed and Abdi Abdirazak, woke to find their daughter missing from the two-bedroom home in Polden House, Windmill Hill.

They spotted the window open at a 45-degree angle and ran downstairs to find Muna receiving treatment from paramedics.

Muna was rushed to Bristol Royal Hospital for Children, where she was pronounced dead a short time later, at 7.51am.

Avon Coroner Maria Voisin reached a conclusion of accidental death at the inquest in Flax Bourton, North Somerset.

"Unfortunately, the exact circumstances of how Muna came by her death and the fall are not clear," Ms Voisin said.

"However, it appears likely that she woke from her sleep, went into the kitchen, climbed onto the chair and then onto the table.

"The window was open and sadly she fell from the window."

Muna did not like her cot, so was sleeping in a double bed with her mother and five-year-old brother Mohamed the night before the incident.

Her father returned to the flat at 11pm to make food for his wife, who was unwell, as the family were observing the Ramadan fast.

Mrs Mohamed, a hospital cleaner, asked her husband to open the windows as the bedroom where they were sleeping had become hot.

The mother-of-two said she fell back to sleep in the bed with her children, before waking at about 7am the following morning.

"I was used to feeling Muna next to me, however Muna was not there," Mrs Mohamed said.

"I was concerned because I didn't know where Muna was. I went into the kitchen, she was not there but the kitchen window was open at 45 degrees.

"I screamed and started shouting 'wake up, wake up, Muna is not in the home'. I went outside and saw the paramedics' car in the car park.

"I saw Muna lying on the floor."

Mr Abdirazak told the hearing he had meant to close all of the windows in the property after his wife fell asleep - but forgot the kitchen as the door was shut.

"She must have opened the kitchen door, climbed onto a small table near the window and reached the window," the full-time father said.

Eamonn Chidzey, a resident at Polden House, was walking to work at 6.45am when he found Muna on a section of grass beneath the flats.

"I assumed the child had fallen," Mr Chidzey said. "I was in shock."

Mr Chidzey said Muna was lying around three feet away from a shopping trolley, which was directly below the kitchen window.

The inquest heard it is possible Muna, who was wearing just a nappy at the time, fell onto the trolley before landing on the grass.

DS John Knight, of Avon and Somerset Police, said: "The kitchen window was left open, the adults were asleep.

"The table and chairs were pushed against the window in such a manner to allow easy access for a child.

"I am satisfied there are no suspicious circumstances as regards to this case and this is a tragic accident."

DS Knight said fingerprints matching Muna's had been found on the window - with numerous palm prints on the interior glass.

"There was a right foot print on the window sill itself," he added.

John Holborn, a building surveyor for Bristol City Council, found a restrictor on the kitchen window was broken.

But he said a child would not have been able to operate the handle of the window to fully open it.

Mr Holborn said Bristol City Council had since replaced the restrictors in the building's windows.

Muna's mother and grandmothers, who attended the inquest, did not wish to speak following the hearing.
