Northumbria Police made the arrests in Jarrow and South Shields late yesterday, Monday, August 24, after detectives from West Midlands Police asked for help in connection with the tragedy in Birmingham, which left 26-year-old Thomas Rogers fatally injured.
Armed police were seen in Baring Street, in the Lawe Top area of South Shields, and in Egerton Road, which runs off Stanhope Road, close to its junction with Gordon Road near Tyne Dock.
A Northumbria Police spokesperson said: “Yesterday our officers executed warrants at two addresses in South Shields to assist an investigation being carried out by another force.”
West Midlands Police today confirmed it has arrested the two women and a man, who are all aged between 24 and 31, in South Tyneside on suspicion of assisting an offender.
They have all been released under investigation.
Mr Rogers was found near the junction of Bristol Road and Mill Pool Way, which is a busy route in Bournbrook to the south-west of Birmingham, at around 4.55pm on Saturday, August 22.
He was rushed to hospital but sadly pronounced dead a short time later, with a post mortem examination finding he died as a result of stab wound to the chest.
Detectives have now charged his brother Samuel Rogers, 30, of St Michaels Street, Sutton-In-Ashfield; Nottinghamshire, and Ryan Hurt, 22, of Peel Crescent, Mansfield, with murder.
They have been remanded to appear before Birmingham Magistrates Court today.
A 40-year-old man has been released with no further action.
