A 22-year-old woman stabbed to death in a taxi has been named as detectives continued to question a man over her murder.

The victim, identified by sources as Natasha Trevis, was knifed repeatedly in a car in Northfield, Birmingham, on Tuesday.

The taxi driver called 999 and residents said paramedics worked for 30 minutes to save her but she was in cardiac arrest when they arrived and died at the scene.

A 28-year-old man was arrested by officers from West Midlands Police shortly after 6pm on Tuesday.

Emergency services arrived at the scene, on Dimsdale Road, near the junction with Hoggs Lane, after receiving a call at 8am.

A hunt to find the attacker was launched and a man named by sources as Junior Saleem Oakes, also known as as Mohammed Saleem (Salim) Junior Oakes, was later arrested.

Police said the suspect was taken into custody after he was found in the garden of a house on Allens Farm in south Birmingham.

Detective Chief Inspector Wayne Jones described the police investigation as "complex and dynamic".

A force spokesman said specially-trained officers were supporting the victim's relatives and the results of a post-mortem examination were awaited.
