A 31-year-old Ghanaian woman has been stabbed to death in south London in the United Kingdom (UK), the Metropolitan Police has confirmed.

Johanita Kossiwa Dogbey was killed on Stockwell Park Walk in Brixton on Monday, May 1, afternoon.

The deceased was the Founder of the Odette Foundation, a charity that worked with people suffering from sickle cell in Ghana and Togo.

According to reports Johanita was talking to her grandmother on the phone while on the way home after buying a birthday present for her mother.

She was a few metres away from her home when a man identified as Mohamed Nur approached from behind and attacked her.

Ms Dogbey was treated by paramedics but pronounced dead at the scene.

Ms Dogbey's family has described her as a "smart, dedicated and loving" woman who "hasn't got one bad bone in her body".

According to the BBC, the suspect "has appeared in court charged with the murder as well as offences connected to other alleged stabbing attacks.

"Mr Nur, 33, is also accused of another count of possession of an offensive weapon and causing grievous bodily harm to three people, last Saturday."

The Metropolitan Police said two women and a man suffered slash injuries in Town Hall Parade, Brixton Road and Acre Lane in Brixton during a one-hour period.

On Friday, Mr Nur, of Bond Way in Vauxhall, appeared at Croydon Magistrates' Court where he was remanded in custody to appear at the Old Bailey next week.
