A man and woman were discovered lying injured on a Kinver street in the early hours of the morning.
Police say the pair were found in Enville Road just after 1am yesterday.
Residents in the area say it is believed they were attacked on their way home from a night out. But police said there was no evidence to suggest that an assault had taken place.
Officers took the man, who is in his 40s, to the Queen Elizabeth Hospital in Birmingham, where his condition was described as stable.
The woman, who is also in her 40s, was discovered a short distance away with head injuries. She was taken to Russells Hall Hospital in Dudley and was released this morning.
Officers say the pair are both believed to be from the local area.
Local policing commander Inspector Jeff Knight said “It’s unclear at this stage of the investigation as to how they sustained their injuries and we are appealing for anyone with information to get in touch with us.
“We have police working within the local area on highly visible patrol to speak to members of the community and they are keen to speak to local residents about any information they might have.”
A resident who didn’t want to be named claimed the couple had been attacked after a night out. He added: “It is quite scary to think that something like this could happen in our village because everybody knows each other.”
Last month residents launched a committee following increased concerns over thefts and anti-social behaviour in the village after the closure of its police station. Officers have not been based full-time at Kinver police station for more than 12 months – instead travelling from up to 20 miles away to attend emergencies.
A meeting is due to be held later this month for residents with Staffordshire’s Police and Crime Commissioner Matthew Ellis.
