The Ministry of Social Development’s office in Masterton is in lockdown again, little more than a week after a firearms incident at the building.

Police are currently guarding the MSD offices on Lincoln Rd, with staff under lockdown.

“At around 12pm, police received reports of a threat made to staff at a premises on Lincoln Rd in Masterton,” police said.

“Staff there chose to go into lockdown.”

There did not appear to be any immediate threat to safety, police said.

Police were “following lines of inquiry in relation to the individual who made the threats”.

Last week, a 25-year-old man was arrested after police received reports a gun had been fired at somebody in Masterton’s MSD office about 12.40pm on May 5.

Nobody was injured in the incident, police said.
