Two people have been arrested after the Armed Offenders Squad was called in to hunt for a "person of interest" in Nelson.
Cordons in the Westbrook Terrace area had now been stood down, a police spokeswoman said.
The AOS was called out for the search earlier this afternoon "as a precaution", she said.
She could now confirm two people had been arrested, and information on their charges could be expected later in the afternoon.
A spokeswoman for St John Ambulance said paramedics were also called in by police to be on standby, but had now been stood down. They did not need to treat anybody.
