A 14-hour stand-off between a gunman and armed police in Oxford has “ended peacefully”, police have said.
Shots were exchanged between the suspect and officers in Paradise Square on Monday before negotiators attempted to end the situation.
A 24-year-old man was arrested on suspicion of attempted murder at about 03:00 BST, police said.
One person is being treated for a non-life threatening injury, South Central Ambulance Service said.
Firearms officers were called at 13:15 BST on Monday after witnesses reported hearing gunfire.
Dean Dwyer, who saw armed police in the street, said: “They were screaming ‘put your hands up’.”
One resident said he heard about 20 shots exchanged, with the gunman “shooting from the balcony” of a home.
“I could hear a female negotiator and an armed response man trying to get him to put his hands up [and] let go of the gun,” he said.
Tourist Janet Borgerson was in the nearby Malmaison hotel when she heard “explosive cracks” before a series of “loud bangs”.
“I thought the second round were firecrackers,” she said.
Fred Dimbleby, editor of Cherwell Online, tweeted footage showing paramedics carrying a stretcher to the scene.
Supt Joe Kidman said: “Thank you to everyone for your understanding and patience while we worked to resolve the incident safely.
“We are grateful for the support of members of the public and local businesses. If you’re coming in to Oxford today you should not experience any further disruption.”
Police began to allow residents to return to their homes on Monday evening after presenting themselves to officers at the police cordon.
All road closures have been lifted in the area, though police remain at the scene.
