A local resident who wished to remain anonymous told the Shropshire Star: “I thought I heard some shouting at about 7pm but didn't think anything of it as it's not unusual around here.
“But then I heard sirens about half an hour later and could see police cars shooting past the front window.
“This carried on for a while and I could tell something was wrong and then I heard more sirens and saw an ambulance.
Chief Inspector Helen Kinrade said: "We understand this will be extremely concerning to the community.
“We would like to reassure the public that the investigation is ongoing and this is believed to be an isolated incident.”
