A jealous boyfriend urged paramedics to come "quickly, quickly" to his girlfriend's help after he fatally stabbed her in their home and turned the knife on himself.

A jury at the Old Bailey yesterday afternoon heard the 999 call made by Pawel Sroka as Joanna Trojniak, 29, laid dying in the living room of their house in Meadvale Road, Addiscombe, on March 23.

Ms Trojniak had told a colleague at Nando's in Colliers Wood just hours earlier that she planned to leave the 34-year-old builder.

She was found with multiple stab wounds to the face, chest and hand just after 9pm by police and paramedics, who had been called by Sroka.

In the short 999 call, he told the handler the address of the couple's terraced house and said his girlfriend - who he incorrectly described as 30 years-old - was lying injured in the living room.

He then hung up the phone.

Officers arrested Sroka at about 10.30pm after finding him bleeding in the driver's seat of his Vauxhaull Vectra in nearby Gordon Crescent, having soiled himself.

By that time Ms Trojniak had been pronounced dead in their house after being found lying in the foetal position.

Prosecutor David Jeremy QC told the jury yesterday morning that Ms Trojniak had been planning to "run away" from Mr Sroka because she feared for her life if she tried to break up with him.

In a witness statement read to the court, neighbour Sharon James described hearing shouting and a "bellowing" male voice just after 8pm on the night of Ms Trojniak's death.

Another neighbour, Graham Kirby, said he heard a "high-pitched scream" before hearing emergency services arrived some minutes later.

Blood was found in a number of rooms in the terraced house, including the upstairs bathroom and the couple's bedroom, forensic scientist Vivienne Basulo-Rodriques told the Old Bailey.

Fingerprints matching Sroka were found in both his and Ms Trojniak's blood on a pink knife block in the kitchen, while both of their blood was also found on a large red kitchen knife.

There were also traces of Ms Trojniak's blood on the living room ceiling, while a nearby rug was sodden with blood.

A Puma hoodie and t-shirt worn by Sroka was found with two matching tear marks, suggesting a struggle, Mr Jeremy said.

Sroka yesterday pleaded guilty to his girlfriend's manslaughter. He denies murder.

Sebastien Kulak, a fellow Polish builder who lived in the couple's house, said in a witness statement to the trial that Sroka was regular cannabis user who smoked the drug to make him "feel very calm".

On the night of Ms Trojniak's death, Mr Kulak had been listening to music on his laptop upstairs when he overheard shouting coming from the ground floor, the court heard.

Later he heard shouts of "police, police", and went downstairs, only to be handcuffed by officers who briefly thought he may be a suspect.

Mr Kulak, who had moved into the house in January without previously knowing the couple, said he had heard them quarrel twice but he was "not the kind of person who gets involved in other people's conversations". 

Mr Jeremy told the court Sroka initially admitted killing his girlfriend, refusing legal advice and telling police: "I've just done it, right."

Later he remained silent with a blanket over his head as police tried to interview him in his cell.

The prosecutor told the jury Sroka was likely to offer a defence of "loss of control" in relation the murder charge, but added: "Anyone who stabbed their girlfriend to death could in the loosest sense be said to have lost control, because it's not something any sane person would do.

"[It is] not designed to be a defence for any man who does not control themselves to kill under emotional pressure.

"Mr Sroka would not be the first or last man upset by the prospect of his girlfriend leaving him."

Mr Jeremy told the jury that Mr Sroka had been "fuelled by a murderous hate, stabbing the woman that was leaving him in the middle of the face". 

The trial continues.
