Tragedy: Mary Shipstone was murdered on her doorstep by her estranged father, whose address was accidentally sent to him by her mother's solicitor

An estranged father who shot dead his daughter was barred from seeing the seven-year-old but was accidentally sent her address by her mother's divorce lawyers, it was revealed today.

Mary Shipstone, was gunned down as she stood next to her mother Lyndsey on the doorstep of her home in Northiam, near Rye, East Sussex, after she returned from school.

Mother and daughter had fled Yasser Alromisse and were given new identities because he was violent and he had been stopped from seeing the child.

Mrs Shipstone had converted to Islam when they married in 2005 - a year after Alromisse entered the UK illegally before claiming asylum - but she later rejected the faith and left her husband, prompting a bitter custody dispute over Mary.

The seven-year-old had just returned from school and was clutching her new violin when Mr Alromisse killed her.

Alromisse, 46, was hiding in the rear of a silver Toyota on the drive at the £300,000 house when he fired the shots on September 11 2014.

The schoolgirl, who was just days away from celebrating her eighth birthday, was taken to King's College Hospital in London but later died of her injuries.

Her father had concealed himself in the car by creating a blind from bin bags and was later found in a pool of blood in the rear of the vehicle, where he had shot himself in the head.

Today a serious case review into her death revealed that five months earlier, the girl's mother, Lyndsey Shipstone, reported to police that her solicitor had inadvertently revealed her new address to Alromisse in legal papers.

Evidence also emerged that details of her previous addresses or identity were given to 46-year-old Alromisse by other bodies, including a bank and the Child Support Agency.

Lyndsey Shipstone has said she feels 'let down and disappointed' by the police taking no action on her new address being disclosed.

She also criticised some of the support she had received during her five-year court battle with Mr Alromisse over custody of their daughter.

She added: 'Because it took so long, people underestimated the seriousness.

'Actually there is a lot of danger - we had the briefest window and then Mary was killed and really nothing was OK.'

Despite the disclosures, the serious case review concluded that no-one could have predicted or prevented the killing in Northiam, near Rye, East Sussex, on September 11 2014.

The couple, who met in Skelmersdale, Lancashire, had married in Liverpool in 2005 after Mrs Shipstone converted to Islam, friends said. She had been a practising Catholic but converted to Islam and quickly became devout.

The couple had a daughter named Yasmin Miriam in September 2001, but she died eight months later.

Mary was later born in 2006 but according to former neighbours, social services had to intervene, with orders barring Alromisse from being alone with his child.

They reconciled briefly in 2010 as Ms Shipstone feared isolation from their mosque if they did not, but the violence worsened and he once locked her and her daughter in the toilet.

She said: 'When I last saw him at court I thought he might try to take her. But it never occurred to me that he would try to murder her.'

The murder has been labelled a 'spite killing' - intended to deprive Ms Shipstone of her daughter as he was losing the custody battle.

The last words Lyndsey said to her daughter as she put the key into her front door were: 'You'll like what I've done to your room.'

She had been living there with her daughter for a year and Mary had settled into her school.

A heartbroken Ms Shipstone, speaking recently said: 'She was the happiest she had been for a long time.

'She was learning the violin and learning to dance and doing all the normal things.

'She was a happy girl and she was developing as a person in her own right, which is what every child deserves.'

Bereft: Lyndsey Shipstone arrives at Hastings Law Courts for the inquest into the death of her daughter last year

Today's report said there was no evidence Alromisse located his daughter and estranged wife through the inadvertent disclosures of the girl's address and her mother's circumstances.

The criminal investigation into Mary's shooting found Alromisse had used 'a variety of covert and illicit means' to try to trace the address and the routine of his daughter, referred to as Child P.

The 73-page serious case review report noted: 'It has not been possible to establish exactly when and how he found out where Child P was living.

'There is no evidence that any professional was aware of this activity, nor did he make any threat to harm Child P or give any indication that he might do so.

'The review has concluded that no professional working with the family could have prevented him acting as he did.'

Mary's death 'was calculated to deprive the mother of her child while at the same time leaving her with a permanent memory of her death', the report said.

And it added that Ms Shipstone believed Alromisse killed their daughter because he feared the outcome of a new round of court hearings would end in him being denied contact.

At an inquest in September last year, East Sussex coroner Alan Craze said the 'thoroughly despicable act of violence' had been 'pre-meditated over a long period of time'.

The inquest heard Ms Shipstone carried Mary to a neighbour's home, where they tried to revive her while waiting for emergency services to arrive.

She was taken to King's College Hospital, London, but later died of her injuries.

A series of recommendations were made in the review, including seeking assurances from agencies that systems were in place surrounding information about vulnerable people that should not be revealed.

A spokesman for the East Sussex Local Safeguarding Children Board said: 'After a thorough independent review, the LSCB concluded, as did the investigating police officers, that the father planned and carried out the killing in a secretive way, using the internet and a range of covert methods to trace the family and obtain the means to carry out the murder.

'There is no evidence that any professional involved with the family prior to these tragic events was aware of this activity. Based on the review, the LSCB concludes that no professional could have prevented him doing what he did.

'The LSCB has also found that professionals did respond diligently to reports of domestic violence, which were all taken seriously and responded to appropriately.
