Police are continuing to question a man after a mother and her 13-year-old son were killed and the woman's husband seriously injured in a stabbing attack.

The family, named locally as Peter and Tracey Wilkinson and their son, Pierce, were found with knife wounds in Stourbridge on Thursday morning.

The suspect, in his 20s, has been arrested on suspicion of murder and wounding. He is understood to be known to the victims but isn't believed to be related to them.

A Land Rover taken from the house was intercepted by police in Norton Road about 30 minutes after the attack.
The 13-year-old boy and his mother were found in a house on Greyhound Lane, Norton, with critical stab wounds at about 8am yesterday morning. The woman was pronounced dead at the scene, while the teenager later died in hospital.
Mr Wilkinson, believed to be a company director for local firm Hill & Smith Ltd, was found in the garden of the house. He remains in hospital with stab wounds to his chest and back.
It's understood the couple also have an older daughter who is attending university.
Police are not looking for anyone else in connection with the attack.
