A woman was rescued by West Midlands Police officers from a flat in Birmingham after she dialled 999 reporting being held captive.
Police received a call at midday from the woman who reported being assaulted and held against her will at a property in Small Heath by a man in possession of a firearm.
A section of Coventry Road was sealed off as West Midlands Police officers, including a firearms unit, contained the property and forced entry.
The woman was found inside and a man, understood to be in his 50s, arrested on suspicion of assault, sexual assault and firearms possession.
Force Incident manager, Chief Inspector Dave Keen, said: “It was a very dynamic, fast-moving incident. The woman sounded petrified on the phone and it was imperative we found her quickly.
“We had reached her within about 20 minutes of receiving the call and a suspect was also swiftly detained. The woman is being checked over by paramedics.
“A firearm was mentioned in the original 999 call; we have yet to recover a firearm but searches of the property continue.”
