The man and woman killed in a suspected ‘hit and run’ in Acocks Green were said to have been a married couple with five children.
The pair had been travelling on a motorbike when it was involved in a collision on Fox Hollies Road on Saturday, June 5.
They were confirmed dead at the scene a short time later.
Reports online claimed the couple were parents to five young children.
West Midlands Police today, June 6, confirmed a 47-year-old man remained in custody after being arrested on suspicion of causing death by dangerous driving.
The force said their initial enquiries suggested a blue Saab may have been involved in the collision but left the scene.
A car matching that description was found nearby, where police arrested the driver.
Det Sgt Paul Hughes, from the force’s collision investigation unit, said: “A man and woman have tragically died and our first thoughts are with their family members and friends at this traumatic time.
