Police officers who failed to uncover a trainee teaching assistant's killing after reports of screaming at her home have been cleared of gross incompetence.

Two constables, who were twice called to 25-year-old Rebecca Sessacar's flat in Waddon on the day she was killed by husband Bulent in 2012, were among five officers issued misconduct notices by the Metropolitan Police.

Mr Sessacar, 30, was jailed for life in February this year for stabbing his wife 58 times with two kitchen knives in their home in Duppas Hill Terrace on December 20, 2012, just days after he had been released without charge having assaulting her.

The Independent Police Complaints Commission launched a two-strand investigation following the killing, probing officers' conduct on the day and their prior involvement with tje violent killer.

Metropolitan Police began unsatisfactory performance procedures against the five officers after IPCC made recommendations following the completion of its investigation in August 2013.

But a Met disciplinary panel did not uphold the allegation of gross incompetence against the two police constables, who had faced the sack if found guilty.

The PCs attended the couple's flat just before 3pm on the day of her death after neighbour heard screams the sound of a body being dragged across the floor.

They found the flat dark and quiet with its curtains drawn, so returned to the police station.

But after a second call from the neighbour they returned to the flat 45 minutes later and looked through the letterbox to see a trail of blood.

They broke the door down to find Mrs Sessacar's body inside along with her husband, who pleaded guilty of manslaughter on the grounds of diminished responsibility in February this year.

The panel the concluded the two constables had conducted an appropriate investigation and took no further action against them.

But a detective constable was disciplined for failing to carry out sufficient enquires Mr Sessacar's home after releasing him on December 18, when Mrs Sessacar declined to press charges for the assault.

The IPCC also recommended a sergeant attend an unsatisfactory performance meeting for failing to ensure the necessary checks were done by the investigating officer and that an inspector receive retraining for failing to give adequate supervision.

A coroner is considering whether to reopen the inquest into the death of Miss Sessacar, who worked at Asda in Beddington.

In February, her mother Sandra Ward said she believed police and mental health staff - who sectioned Mr Sessacar in September 2012 but released him from hospital two weeks later - could have saved her daughter.

She said: "Bulent should not have been let out on bail after he assaulted Rebecca on the Tuesday before he killed her.

"I hope lessons are learned from this."
