The officer allegedly left after Jasionis reassured him

A Pc who allegedly left a woman with her rapist while responding to a 999 call in London is being investigated by the Metropolitan Police.

Pc Matthew Harris went to the victim's flat in Woolwich last November but allegedly left without making inquiries when Vitas Jasionis reassured him.

Jasionis, 54, of Southwark, was found guilty of raping the 32-year-old woman at Woolwich Crown Court on Monday.

Pc Harris has been referred to the directorate of professional standards.

The court heard the officer went to the flat in Ruston Road after a neighbour called 999 to report the screams of a woman.

Wanted for murder

When he knocked on the door Jasionis answered and reassured the officer, who then allegedly left without making further inquiries.

Hours later the victim called the police, but by then she had been raped again, the court was told.

Jasionis, who will be sentenced later, was arrested at the scene.

His brother, Antanas Jasionis, 50, was cleared of rape, but is due to be extradited to Lithuania where he is wanted for murder.

A spokesman for the Met said the officer had been referred to the force's directorate of professional standards.

The inquiry comes after police watchdog the Independent Police Complaints Commission warned that officers could be prosecuted for making blunders in two serial sex attacker cases - street stalker Kirk Reid and taxi-driving rapist John Worboys.
