Three people arrested at the end of a two-day armed siege, which saw one man tasered by police, are due to be questioned by detectives.
The stand-off at a home in Norwich ended after 32 hours of negotiations, a Norfolk Police spokesman said.
Police were called at 9am on Friday to reports of a man with a gun inside a property with a woman and another man.
Specialist firearm officers, dog handlers and police negotiators cordoned off an area around the house in Badger Road, Costessey, after a call was received from a concerned member of the public.
The incident was resolved at 5pm on Saturday.
"Following lengthy negotiations the three occupants came out of the property one by one at about 5pm," said a police spokesman. "The final man aged in his 40s, who is believed to have instigated the incident, was tasered to effect a safe and secure arrest."
The man was arrested on suspected firearms offences and the other man and woman, both in their 40s, were arrested on suspicion of wasting police time. All three have been taken into custody where they will be questioned.
Inspector Chris Brooks said: "Officers attended the area responding to an incident to ensure and maintain community safety.
"The level of response was deemed necessary to ensure a safe and peaceful resolution, enabling the community to return to daily life.
"We would like to thank the local community for their patience and understanding during this long incident."
