Nur, 33, is accused of killing Dogbey, 31, on May 1 and other offenses related to other suspected stabbing incidents.
In an unprovoked stranger attack, a man is suspected of fatally slashing a woman in the neck with a homemade blade.
In broad daylight in Brixton, south London, Mohamed Nur, 33, is accused of approaching Johanita Kossiwa Dogbey, 31, from behind and striking her with a sharp object.
Nur was charged with her murder on Tuesday when she showed up at the Old Bailey after hurting three other bystanders the previous day and possessing weapons consisting of scissor blades and shattered mirror glass.
According to prosecutor Julian Evans, Dogbey suffered stab wounds that led to her death and was “completely unprovokedly attacked on.”
He told the court: “There is no suggestion she and the defendant were known to one another.”
On May 1, Dogbey was wandering alone himself in Brixton’s Stockwell Park Walk after traveling into central London for some shopping. A man in all dark attire attacked her from behind, and she was killed instantly.
Sharp force trauma to the neck was determined to be the cause of death after a postmortem examination. Nur is accused of attacking three people in short succession in Brixton two days prior, on April 29, at around 11.30 p.m.
All three are said to have been attacked “without warning, without provocation, and seemingly at random.” They allegedly sustained facial or cheek injuries.
After being detained by police on Brixton High Street, Nur was taken into custody on suspicion of having a weapon made out of a piece of shattered mirror.
On April 29, he was charged with killing Dogbey, three charges of intentionally causing great bodily harm, and two counts of possessing an offensive weapon that had a blade made of glass or scissors on May 1 and May 2, respectively.
In the dock of the Old Bailey on Tuesday, Nur, who was residing in a hostel in Vauxhall, south London, spoke simply to establish his identity. Family members of Dogbey sat in the court’s well for the preliminary hearing.
