Families have described how they were woken up in the early hours after a man was shot in their neighbourhood.
Armed officers were called to Moutter Close, in Horden, County Durham, at around 1.45am on Sunday after receiving a report of the incident.
The victim was treated by paramedics and taken to hospital with serious injuries.
A man was arrested on suspicion of attempted murder and two women were also in custody on suspicion of conspiracy to commit murder.
On Sunday morning, a cordon remained around Moutter Close while investigations continued. Forensics officers wearing white suits also arrived in the street to gather evidence.
People in the area said they were shocked by what had happened.
One mum said: "I was woken up early in the morning by a commotion outside and could see police officers and a police van when I looked out.
"I have no idea what's been going on but it was worrying to see the police, especially when there are children living here."
Another mum, who lives nearby, said: "This is really scary, it's right on our doorstep. There are lots of families with bairns around here.
"It's not the kind of thing you want where you live."
Durham Constabulary is appealing for any witnesses to contact them as soon as possible.
DCI Stephen Thubron said: "I am appealing to anyone within this community who may have witnessed this incident or have any information to come forward and speak to us.”
