A 21-year-old man has been sentenced to life for killing his ex-partner and her mother in a frenzied knife attack after his second secret family was discovered.

Janbaz Tarin killed Raneem Oudeh, 22, and her mother Khaola Saleem outside Mrs Saleem's home in Northdown Road, Solihull, West Midlands, shortly after midnight on August 27.

Tarin, of Evelyn Road in Sparkhill, Birmingham, had armed himself with a knife after a public row with Ms Oudeh, who was his wife under Islamic law.

He then fled, leading police on a three-day manhunt before his dramatic capture by officers.

Ms Oudeh had dumped her husband in the weeks before his attack after learning he had three children and a secret wife who was pregnant with a fourth child in Afghanistan.

Ms Oudeh had secured a non-molestation order against him after he smashed her phone on August 10.

But he flouted the ban and in the hours leading up to the assault Ms Oudeh made three calls to police.

She was on the phone to a 999 call handler when Tarin struck.

When Mrs Saleem attempted to save her daughter from the onslaught, she too was fatally stabbed by callous Tarin - who fled the scene before officers arrived.

Tarin has been sentenced to life with a minimum term of 32 years at Birmingham Crown Court on Monday after admitting the double murder of his ex-partner and her mother.

The head of West Midlands Police's CID described the crime as "one of the most brutal and heart-rending" he had seen in 150 homicides.

It came as the family of Ms Oudeh, a mother of one, revealed Tarin "hassled" the 22-year-old into marriage after they met at Solihull College, where he enrolled after lying about his age.

Chillingly, he later told her "when I saw you, I said this is mine".

But after being wed, Tarin turned violent towards Ms Oudeh and the couple had split "months" before the killing, according to her aunt Nour Norris.

She said: "He used to threaten her many times 'if you leave me, I will kill you and your family'.

"Unfortunately she only told us that at the end because she knew, she couldn't cope with him anymore with all the violence he was giving her and she knew that the police and authority and everybody wasn't really helping her so she felt like she could say those things.

"One day she said to me, Auntie, I feel my life's going to end.

"I said 'don't say that'.

"That was few weeks before she was murdered."

The split was triggered, in part, when she became aware Tarin had lied to her from the start; about being much older than he claimed, and about a secret family he had back in the Middle East.

Mrs Norris said her niece got a court injunction against him, with the help of Mrs Saleem, two weeks before the killing.

On at least one previous occasion he had broken into the house at Northdown Road to get at Ms Oudeh, she added.

She also said Tarin was "well-known" to police for his violent abuse of Ms Oudeh, in the months leading up the murder.

The 39-year-old said: "After a few months marriage to him, she decided he's not the right man for her."

Trapped in the marriage, Ms Oudeh kept a brave face on her relationship, hiding the abuse from relatives.

Mrs Norris said: "After she got married to him, she realised he was a good liar.

She added: "He was removed from the college because of Raneem, because she realised he's got a family abroad and he's lied to her.

"I think after a while he tried to get close to her, as in 'I want to marry you' and when she realised his age - that he's married and got kids abroad - she didn't want that relationship."

Mrs Norris said: "When she realised she's made a big mistake she felt she can't go back, because he's very strong.

"But she didn't tell us."

She added: "We understood she was trying to protect us, because he was trying to frighten her by saying 'if you leave, I have your family, all under my finger' as in he's threatening her with her family."

Eventually, Mrs Saleem told her daughter "we're going to do the right thing, go to the court, get a court order", according to Mrs Norris.

"That's exactly what my sister did, the right thing," she added.

"What any mother would do. She tried to protect her by doing the right thing."

She added: "They felt very strong after they had the court order, but unfortunately it wasn't enough to save their lives."

Ms Oudeh's son, two-and-a-half years old, is now living with Mrs Norris.

Asked if she believed the police and authorities had failed to do enough that night to stop Tarin, and in the months beforehand to protect the victim, Mrs Norris replied: "Yes we do."

"We do feel that and we feel there's a lot of women out there as well probably going through the same thing, who agree with us."

After the attack, Tarin fled in his white van and remained on the run for three days until a member of the public spotted him and tipped off police.

Mrs Norris said: "That last call, the police were on the phone so they knew she was getting harmed but we couldn't believe they couldn't locate him straight away.

"Because they knew about it there and then so that was one of the things that made us feel more unhappy, more sad, more let down by the authorities."

The couple met at Solihull College, when she first arrived from Syria.

Mrs Norris said: "Her mum has been here for 16 years, and because of the war in Syria, Raneem came to reunite with her family, and they were very happy,

"She was very happy, excited, I remembered taking her down to college and introducing her.

"She was very happy to be there, be with her mum, start a new life, away from it all.

"And here he was, sitting in the classroom, pretending (about) his age - he's much older.

"He said to her later on, she told me, that 'when I saw you, I said this is mine, she is for me'.

"She is very pretty and she's got the joy and love of the world, so when you see her you have to love her - but no one deserved to be loved in that way."

The Independent Office of Police Conduct is investigating the circumstances surrounding the police response to the murders, after a self-referral by West Midlands Police.
